1 00:00:12,000 --> 00:00:13,000 Hello, friends. 2 00:00:13,000 --> 00:00:18,000 Today I will tell you about national instruments. 3 00:00:18,000 --> 00:00:21,000 USB 6009. 4 00:00:21,000 --> 00:00:32,000 It is a DAC card, as you see over here on this side, we have different pins like ground plus five 5 00:00:32,000 --> 00:00:37,000 plus 2.5 and some other digital ports. 6 00:00:37,000 --> 00:00:47,000 As you see over here, we have pin zero port zero, then pin zero port zero pin number one. 7 00:00:47,000 --> 00:00:57,000 After that, up to seven we have port one pin zero, port, one pin, one port, one pin two, and then 8 00:00:58,000 --> 00:01:01,000 we have port one pin three. 9 00:01:01,000 --> 00:01:04,000 And after that we have paf I zero. 10 00:01:04,000 --> 00:01:07,000 All these are my digital pins. 11 00:01:08,000 --> 00:01:11,000 On the other side we have analog pins. 12 00:01:11,000 --> 00:01:20,000 As you see, I stands for analog input zero in USB 6009. 13 00:01:20,000 --> 00:01:30,000 We have four differential analog inputs and eight single ended inputs, analog inputs. 14 00:01:30,000 --> 00:01:36,000 And other than this, we have, as you see over here, analog output, port zero, analog output, port 15 00:01:36,000 --> 00:01:42,000 one and ground analog output A0 stands for analog output. 16 00:01:42,000 --> 00:01:48,000 So this is some basic introduction as you see over here. 17 00:01:48,000 --> 00:01:55,000 Eight inputs 14 bit function input output DAC card it is. 18 00:02:20,000 --> 00:02:20,000 Hello, friends. 19 00:02:21,000 --> 00:02:37,000 Today I will tell you how to connect or how to use any USB 6009 DAC card for generating digital signal. 20 00:02:37,000 --> 00:02:47,000 For that purpose, first of all, you have to connect your USB 6009 DAC card to your PC. 21 00:02:47,000 --> 00:02:51,000 When you connect this through the USB, it will blink. 22 00:02:51,000 --> 00:02:53,000 As you see in the video. 23 00:02:54,000 --> 00:03:07,000 So for here I have a breadboard as you see I just some jumping wire or you can say jumper wires. 24 00:03:08,000 --> 00:03:14,000 These are my male to male jumper wires and I have one led. 25 00:03:15,000 --> 00:03:19,000 I just use it for generating a signal. 26 00:03:20,000 --> 00:03:30,000 Right now I just generate a signal digital signal using this and I 6009 card to glow the Led. 27 00:03:31,000 --> 00:03:36,000 So just go to the software part. 28 00:03:37,000 --> 00:03:43,000 So just create a new as you see over here this is my UI. 29 00:03:45,000 --> 00:03:52,000 Now I just go to any DMX toolbox. 30 00:03:53,000 --> 00:04:00,000 So in this box I just use different nodes. 31 00:04:01,000 --> 00:04:11,000 So right click measurement, input output and I let Max just lock it. 32 00:04:13,000 --> 00:04:18,000 As you see over here, this is my block diagram window and this is my front panel window. 33 00:04:18,000 --> 00:04:21,000 So first I just create channel. 34 00:04:21,000 --> 00:04:25,000 I want to work with third signals. 35 00:04:25,000 --> 00:04:32,000 So just select this output because I want to just generate a signal. 36 00:04:33,000 --> 00:04:43,000 Now just drag and drop, start the task, connect it to error out. 37 00:04:44,000 --> 00:04:55,000 Now I just want to right, so just put over here. 38 00:04:55,000 --> 00:04:58,000 Next, I want to stop the task. 39 00:05:03,000 --> 00:05:09,000 Connect it and I want to do it many times. 40 00:05:09,000 --> 00:05:15,000 So that's why I just put a while loop over the writing task. 41 00:05:15,000 --> 00:05:19,000 And the writing task is my digital writing. 42 00:05:19,000 --> 00:05:24,000 So select single channel, single sample pooling line. 43 00:05:24,000 --> 00:05:39,000 Okay, So over here on the line is just create a constant so that as you see over here, the name of 44 00:05:39,000 --> 00:05:43,000 the device is Dev one port 090. 45 00:05:43,000 --> 00:05:50,000 If you want to check out what device is connected, you just go to an Imax. 46 00:05:52,000 --> 00:06:02,000 You can check your hardware device using this and Imax if it is some creating some problem. 47 00:06:02,000 --> 00:06:05,000 So I just go to Imax. 48 00:06:09,000 --> 00:06:15,000 So over here in the device and interface, just click over here. 49 00:06:20,000 --> 00:06:20,000 Here. 50 00:06:20,000 --> 00:06:24,000 You get all the information regarding your system right now. 51 00:06:24,000 --> 00:06:31,000 My system is Intel core i3 1.7GHz speed. 52 00:06:32,000 --> 00:06:35,000 It is the information of my system. 53 00:06:35,000 --> 00:06:36,000 Okay. 54 00:06:36,000 --> 00:06:43,000 And over here, this is the device which is connected to my system. 55 00:06:46,000 --> 00:06:50,000 So over here, this is the serial number and it is present. 56 00:06:50,000 --> 00:06:59,000 If I disconnect it, you see it is not present, so I just connect it again. 57 00:06:59,000 --> 00:07:01,000 So now it is present. 58 00:07:01,000 --> 00:07:06,000 Okay, so I just close it. 59 00:07:07,000 --> 00:07:21,000 So right now I just use old 090 or device one, select it and I just use a simple error handler from 60 00:07:21,000 --> 00:07:22,000 the dialog box. 61 00:07:23,000 --> 00:07:24,000 If some error is there, 62 00:07:27,000 --> 00:07:33,000 now you have to select or create signal. 63 00:07:33,000 --> 00:07:35,000 So I just use a push button. 64 00:07:37,000 --> 00:07:38,000 It will generate signal. 65 00:07:39,000 --> 00:07:40,000 True or false? 66 00:07:42,000 --> 00:07:43,000 Connect it. 67 00:07:43,000 --> 00:07:49,000 So over here, this is the signal from the LCD. 68 00:07:49,000 --> 00:07:55,000 And over here, this is my control button to stop the loop. 69 00:07:58,000 --> 00:07:58,000 So 70 00:08:01,000 --> 00:08:02,000 this is my stopping button. 71 00:08:05,000 --> 00:08:08,000 I just use one led. 72 00:08:08,000 --> 00:08:15,000 Virtual led to indicate the status inside the software. 73 00:08:16,000 --> 00:08:18,000 So over here, this is my lead. 74 00:08:20,000 --> 00:08:21,000 So connected. 75 00:08:23,000 --> 00:08:27,000 So when it is high, high signal goes to the outer world. 76 00:08:27,000 --> 00:08:30,000 When it is low, low signal goes to the outer world. 77 00:08:30,000 --> 00:08:33,000 Now go to the hardware part. 78 00:08:33,000 --> 00:08:41,000 As you see over here in this case, p 0.0. 79 00:08:41,000 --> 00:08:45,000 This is my port 090, so I just connect it. 80 00:08:48,000 --> 00:08:49,000 With jumper wire. 81 00:08:52,000 --> 00:08:53,000 Okay. 82 00:09:02,000 --> 00:09:03,000 So over here. 83 00:09:03,000 --> 00:09:06,000 This is my line zero. 84 00:09:07,000 --> 00:09:11,000 Now I just need a ground signal also. 85 00:09:31,000 --> 00:09:33,000 So this is my ground signal. 86 00:09:33,000 --> 00:09:36,000 As you see over here, this is my led. 87 00:09:37,000 --> 00:09:38,000 This is my positive leg. 88 00:09:38,000 --> 00:09:40,000 This is my negative leg. 89 00:09:40,000 --> 00:09:41,000 Just. 90 00:09:43,000 --> 00:09:43,000 What? 91 00:09:43,000 --> 00:09:44,000 Over here. 92 00:09:47,000 --> 00:09:49,000 So this is my posting. 93 00:09:52,000 --> 00:09:55,000 And this is my negative. 94 00:10:05,000 --> 00:10:06,000 Okay. 95 00:10:06,000 --> 00:10:09,000 So when you hit on run button. 96 00:10:15,000 --> 00:10:19,000 And signal is high right now. 97 00:10:21,000 --> 00:10:23,000 4090. 98 00:10:58,000 --> 00:11:04,000 So as you see, when it is high, signal goes high. 99 00:11:04,000 --> 00:11:06,000 When it is low, signal goes low. 100 00:11:08,000 --> 00:11:14,000 Okay, So this is how you can generate a digital signal using 101 00:11:17,000 --> 00:11:21,000 any USB 6009 deck card. 102 00:11:24,000 --> 00:11:24,000 Thank you. 103 00:11:49,000 --> 00:11:50,000 In today's lecture. 104 00:11:50,000 --> 00:11:57,000 Today's lecture we just discussed how to acquire digital signal. 105 00:11:58,000 --> 00:12:06,000 As you see over here in my USB 6009 DAC card, we have ground signal. 106 00:12:06,000 --> 00:12:14,000 This is my ground signal and it is present at 32 number pin and we have plus five volt signal also. 107 00:12:15,000 --> 00:12:19,000 So I just use it as a digital hi signal. 108 00:12:20,000 --> 00:12:23,000 I just use it as a digital low signal. 109 00:12:23,000 --> 00:12:34,000 So 31 pin will give me high signal, 32 pin will give me low signal and I am just using port 090. 110 00:12:35,000 --> 00:12:40,000 So now I just go to the software part over here. 111 00:12:40,000 --> 00:12:48,000 Just go to measurement input output and I take Max, lock it. 112 00:12:49,000 --> 00:12:56,000 So over here, first, create channel digital input, select digital input. 113 00:12:56,000 --> 00:13:00,000 Right now I just want to read the signal. 114 00:13:00,000 --> 00:13:04,000 And the signal is my digital single channel. 115 00:13:04,000 --> 00:13:06,000 Single sample line one. 116 00:13:07,000 --> 00:13:12,000 Okay, Start the task, connect task into task out. 117 00:13:17,000 --> 00:13:19,000 Of every block. 118 00:13:19,000 --> 00:13:20,000 Or you can say every node. 119 00:13:21,000 --> 00:13:22,000 Stop the task. 120 00:13:28,000 --> 00:13:30,000 No, over here. 121 00:13:30,000 --> 00:13:31,000 I just use. 122 00:13:34,000 --> 00:13:38,000 Simple error handler if some error is there. 123 00:13:40,000 --> 00:13:44,000 Use while loop for continuous reading. 124 00:13:47,000 --> 00:13:48,000 Create control over here. 125 00:13:51,000 --> 00:13:53,000 Close it over here. 126 00:13:54,000 --> 00:14:00,000 Create constant to select the pin over here. 127 00:14:00,000 --> 00:14:03,000 Device 04090 is selected. 128 00:14:04,000 --> 00:14:16,000 Now you have to just create an indicator in this case because output signal is available outside the 129 00:14:16,000 --> 00:14:16,000 world. 130 00:14:17,000 --> 00:14:18,000 You just read it. 131 00:14:19,000 --> 00:14:22,000 The signal is high or low. 132 00:14:22,000 --> 00:14:25,000 This is my line zero. 133 00:14:26,000 --> 00:14:27,000 Okay. 134 00:14:31,000 --> 00:14:33,000 And this is my stop button. 135 00:14:35,000 --> 00:14:42,000 So now this is my line zero. 136 00:14:43,000 --> 00:14:46,000 I just connect high signal to it. 137 00:14:47,000 --> 00:14:56,000 So when I hit on run button, as you see, Led goes on in the software. 138 00:14:57,000 --> 00:15:07,000 When I remove it and just connect ground pin to it, led goes low again. 139 00:15:07,000 --> 00:15:13,000 When I connect to pin two, it goes high. 140 00:15:13,000 --> 00:15:27,000 Basically, if you are not connecting your port with your or you can say if you open your port after 141 00:15:27,000 --> 00:15:32,000 initializing it, it is in pull up condition. 142 00:15:32,000 --> 00:15:43,000 As you see when I am not connecting any led, it is high when I connect ground pin to it, it goes low. 143 00:15:43,000 --> 00:15:48,000 So it is in pull up condition. 144 00:15:48,000 --> 00:15:48,000 Okay. 145 00:15:48,000 --> 00:15:56,000 So basically for the pull up and pull down conditions, you can check out my other videos or you can 146 00:15:56,000 --> 00:15:59,000 search over Internet also. 147 00:15:59,000 --> 00:16:11,000 Basically, every hardware, like any USB 6009 DAC Card, Arduino, Raspberry Pi, all are initialized 148 00:16:11,000 --> 00:16:13,000 with two conditions. 149 00:16:13,000 --> 00:16:15,000 Pull up condition, pull down condition. 150 00:16:15,000 --> 00:16:18,000 If pull up condition is there. 151 00:16:18,000 --> 00:16:22,000 If you initialized your port and just open it. 152 00:16:22,000 --> 00:16:24,000 No signal is connected with this. 153 00:16:24,000 --> 00:16:29,000 In this case they are in case of pull up. 154 00:16:29,000 --> 00:16:33,000 They are at initially high condition. 155 00:16:33,000 --> 00:16:38,000 If it is pull down condition, in that case it is in low condition. 156 00:16:38,000 --> 00:16:47,000 So or you can say if the port is open, always high signal is there in case of pull up condition and 157 00:16:47,000 --> 00:16:50,000 pull down condition, low signal is there. 158 00:16:50,000 --> 00:17:00,000 Okay so when I connect ground signal goes, signal goes low and when I connect high signal high is there. 159 00:17:00,000 --> 00:17:07,000 So this is how you can read digital signal using any USB 6009 DAC card. 160 00:17:09,000 --> 00:17:09,000 Thank you. 161 00:17:35,000 --> 00:17:35,000 Hello, friends. 162 00:17:36,000 --> 00:17:41,000 In today's lecture, I will show you how to read. 163 00:17:42,000 --> 00:17:44,000 Pistol Non-taster. 164 00:17:45,000 --> 00:17:50,000 How to read Analog signal using any USB 6009 DAC card. 165 00:17:51,000 --> 00:17:58,000 For that purpose, I just create a new video over here. 166 00:17:58,000 --> 00:18:05,000 As you see, this is my V, This is my front panel window. 167 00:18:05,000 --> 00:18:07,000 This is my block diagram window. 168 00:18:07,000 --> 00:18:11,000 I just move it over here. 169 00:18:13,000 --> 00:18:17,000 Because the front block diagram is large. 170 00:18:18,000 --> 00:18:25,000 So for that purpose, just go to measurement input output and Max, lock it over here. 171 00:18:25,000 --> 00:18:27,000 So first create channel. 172 00:18:28,000 --> 00:18:32,000 I want to just read analog input voltage. 173 00:18:32,000 --> 00:18:35,000 Create task over here. 174 00:18:36,000 --> 00:18:43,000 PIN number I Analog input zero is selected on my hardware. 175 00:18:43,000 --> 00:18:45,000 I just select this one. 176 00:18:45,000 --> 00:18:47,000 Start the task. 177 00:18:48,000 --> 00:18:53,000 So connect task into task out error into error out other end. 178 00:18:53,000 --> 00:19:00,000 Stop the task and in between just read analog signal. 179 00:19:01,000 --> 00:19:04,000 So connect it. 180 00:19:07,000 --> 00:19:08,000 Like this. 181 00:19:08,000 --> 00:19:09,000 Go to dialog box. 182 00:19:09,000 --> 00:19:11,000 Simple error handler. 183 00:19:14,000 --> 00:19:20,000 I just make visible labels control you. 184 00:19:24,000 --> 00:19:29,000 No, I want to just read it continuously. 185 00:19:30,000 --> 00:19:33,000 Create control. 186 00:19:33,000 --> 00:19:34,000 Control you. 187 00:19:35,000 --> 00:19:36,000 So now over here. 188 00:19:36,000 --> 00:19:39,000 This is my data available. 189 00:19:39,000 --> 00:19:44,000 So I just use a gauge. 190 00:19:45,000 --> 00:19:54,000 So as you see, the range is five volt because on board I have five volt signal. 191 00:19:55,000 --> 00:19:59,000 So this is my signal over here. 192 00:19:59,000 --> 00:20:02,000 This is my port potentiometer. 193 00:20:03,000 --> 00:20:05,000 I just use. 194 00:20:07,000 --> 00:20:09,000 Connect this. 195 00:20:22,000 --> 00:20:30,000 It increased the size of this connect this control you. 196 00:20:31,000 --> 00:20:33,000 So now the code is ready. 197 00:20:34,000 --> 00:20:38,000 So goes to the hardware part. 198 00:20:38,000 --> 00:20:41,000 As you see over here, this is my potentiometer. 199 00:20:42,000 --> 00:20:43,000 It has three pins. 200 00:20:44,000 --> 00:20:47,000 As you see, these are three pins. 201 00:20:47,000 --> 00:20:50,000 One end is connected to the high voltage. 202 00:20:50,000 --> 00:20:54,000 One is connected to the ground, and the middle one is my wiper. 203 00:20:54,000 --> 00:21:01,000 And it is controlled according to this Rotary Park. 204 00:21:01,000 --> 00:21:03,000 Or you can say Shaft. 205 00:21:03,000 --> 00:21:11,000 So I just connect it to my breadboard over here. 206 00:21:11,000 --> 00:21:13,000 Blue one is my plus five volt. 207 00:21:13,000 --> 00:21:15,000 This is connected to the one end. 208 00:21:16,000 --> 00:21:20,000 And in this side I have analog input signals. 209 00:21:21,000 --> 00:21:23,000 So first one is my ground pin. 210 00:21:24,000 --> 00:21:26,000 Second one is my I zero. 211 00:21:26,000 --> 00:21:34,000 I just connect I zero to my middle one of the potentiometer and I just connect ground to the other end 212 00:21:34,000 --> 00:21:35,000 of the potentiometer. 213 00:21:35,000 --> 00:21:37,000 That is third one left pin. 214 00:21:37,000 --> 00:21:42,000 And I also connect I four because I'm using differential mode. 215 00:21:42,000 --> 00:21:51,000 Okay, so right now over here, these is my ground and orange one is I four and yellow one is my I zero. 216 00:21:51,000 --> 00:21:57,000 So when I hit on run button, as you see over here, there is some voltage. 217 00:21:57,000 --> 00:22:00,000 If you want to check how much is this? 218 00:22:00,000 --> 00:22:02,000 So just visible. 219 00:22:02,000 --> 00:22:04,000 It's digital display. 220 00:22:05,000 --> 00:22:14,000 So I don't run button as you see, when I move it, value goes high. 221 00:22:14,000 --> 00:22:16,000 Right now it is extremely high. 222 00:22:17,000 --> 00:22:18,000 Now it is five volt. 223 00:22:22,000 --> 00:22:25,000 And this is zero. 224 00:22:26,000 --> 00:22:36,000 So this is how you can interface a potentiometer to create analog signals. 225 00:22:36,000 --> 00:22:41,000 Right now, analog signals are read by my DAC card. 226 00:22:42,000 --> 00:22:45,000 In this case, I'm using a single analog signal. 227 00:22:46,000 --> 00:22:58,000 Okay, so this is how you can read an analog signal or how you can interface a potentiometer to your 228 00:22:58,000 --> 00:22:59,000 tech card. 229 00:22:59,000 --> 00:23:00,000 Okay. 230 00:23:00,000 --> 00:23:07,000 In place of that card, if I just remove the DAC card right now, random signal is there. 231 00:23:08,000 --> 00:23:12,000 If you want to check what is goes. 232 00:23:12,000 --> 00:23:17,000 So as you see right now, I just connect positive signal. 233 00:23:17,000 --> 00:23:19,000 So now it is high. 234 00:23:20,000 --> 00:23:24,000 I I'm just connecting A02 plus five volt. 235 00:23:24,000 --> 00:23:26,000 Right now it goes high. 236 00:23:26,000 --> 00:23:38,000 If I just connect because on board I have 2.5 signal also there, as you see over here, this is my 237 00:23:38,000 --> 00:23:39,000 plus 2.5 signal. 238 00:23:40,000 --> 00:23:43,000 It is next to my five volts. 239 00:23:44,000 --> 00:23:45,000 So I just connect it. 240 00:23:50,000 --> 00:23:53,000 And check what goes on. 241 00:23:55,000 --> 00:23:59,000 So I just make it tight. 242 00:24:00,000 --> 00:24:04,000 So now I just remove five. 243 00:24:05,000 --> 00:24:10,000 I just connect plus 2.5 to the I zero. 244 00:24:10,000 --> 00:24:13,000 As you see, plus 2.5V signal is there. 245 00:24:13,000 --> 00:24:21,000 So this is how you can acquire analog signal using an I USB 6009 DAC card. 246 00:24:23,000 --> 00:24:24,000 Thank you. 247 00:24:48,000 --> 00:24:54,000 In this video, you will work out with multiple digital signals. 248 00:24:54,000 --> 00:24:58,000 Right now I just read multiple digital signals. 249 00:24:58,000 --> 00:25:03,000 So over here I have my previous code. 250 00:25:03,000 --> 00:25:10,000 So over here you just select browse multiple lines. 251 00:25:10,000 --> 00:25:14,000 Right now I'm selecting line zero, line one, line two, line three. 252 00:25:14,000 --> 00:25:15,000 Just select it. 253 00:25:15,000 --> 00:25:18,000 As you see it goes from zero colon three. 254 00:25:19,000 --> 00:25:27,000 Now in this case, you just delete this one because right now we have multiple signals. 255 00:25:27,000 --> 00:25:34,000 So over here you just go to digital single channel, single sample, one dimensional lines. 256 00:25:35,000 --> 00:25:35,000 Okay? 257 00:25:35,000 --> 00:25:40,000 So right now just go to index array. 258 00:25:40,000 --> 00:25:42,000 You have to select multiple signals. 259 00:25:42,000 --> 00:25:47,000 So just drag over here is my data. 260 00:25:47,000 --> 00:25:53,000 Or you can say one dimensional data of four signals zero, one, two, three. 261 00:25:53,000 --> 00:25:57,000 And over here you have to select different pins. 262 00:25:57,000 --> 00:26:02,000 So create constant pin zero, create constant pin one. 263 00:26:02,000 --> 00:26:04,000 Create constant pin two. 264 00:26:05,000 --> 00:26:07,000 Create constant pin three. 265 00:26:08,000 --> 00:26:08,000 Okay. 266 00:26:08,000 --> 00:26:13,000 So control you to minimize the space. 267 00:26:13,000 --> 00:26:17,000 So now I just use four Led buttons. 268 00:26:17,000 --> 00:26:25,000 So in the classics I'm just using more attractive Led over here. 269 00:26:26,000 --> 00:26:27,000 This is my Led. 270 00:26:28,000 --> 00:26:31,000 You can also change the color of this one. 271 00:26:31,000 --> 00:26:34,000 So this is my, let's say 0.90. 272 00:26:37,000 --> 00:26:45,000 Then I just check multiple LEDs over here. 273 00:26:46,000 --> 00:26:51,000 So these are my over here. 274 00:26:51,000 --> 00:26:57,000 This is my Led one line, one not led. 275 00:26:58,000 --> 00:27:03,000 This is my line two and this is my line three. 276 00:27:04,000 --> 00:27:09,000 Okay, So if you want to change the color, you just select it. 277 00:27:09,000 --> 00:27:11,000 Go to the properties. 278 00:27:13,000 --> 00:27:17,000 You can change the glowing color of it also. 279 00:27:17,000 --> 00:27:21,000 So right now, the glowing color of this is red. 280 00:27:21,000 --> 00:27:24,000 And press. 281 00:27:24,000 --> 00:27:24,000 Okay. 282 00:27:25,000 --> 00:27:35,000 And again, if you want to change the glowing color of this and also, let's say it will glow with this 283 00:27:35,000 --> 00:27:35,000 color. 284 00:27:36,000 --> 00:27:37,000 Okay. 285 00:27:37,000 --> 00:27:48,000 So now I just put this LEDs inside the loop and I want to connect these LEDs with it's number. 286 00:27:48,000 --> 00:27:51,000 So over here, this is my 010. 287 00:27:52,000 --> 00:27:53,000 So this is my one. 288 00:27:55,000 --> 00:27:59,000 This is my space is very less over here. 289 00:28:00,000 --> 00:28:08,000 So this is my line three and this is my line to control you. 290 00:28:10,000 --> 00:28:14,000 So this is my code for multiple signals. 291 00:28:15,000 --> 00:28:17,000 Now go to the hardware part. 292 00:28:17,000 --> 00:28:21,000 So over here, Port zero is connected. 293 00:28:21,000 --> 00:28:25,000 Port three is connected, not port. 294 00:28:25,000 --> 00:28:27,000 Line three is connected. 295 00:28:27,000 --> 00:28:30,000 So I just connect line two. 296 00:28:32,000 --> 00:28:35,000 So now line two is also connected. 297 00:28:36,000 --> 00:28:39,000 I just go with line one. 298 00:28:41,000 --> 00:28:43,000 So now line one is also connected. 299 00:28:43,000 --> 00:28:48,000 So over here, these are my different signals. 300 00:28:48,000 --> 00:28:49,000 So this is my line. 301 00:28:49,000 --> 00:28:52,000 Zero line one, line two, line three. 302 00:28:52,000 --> 00:28:54,000 And this is my high signal. 303 00:28:54,000 --> 00:28:55,000 This is my low signal. 304 00:28:55,000 --> 00:29:02,000 So let's say initially I just make all the LEDs low. 305 00:29:06,000 --> 00:29:11,000 Or you can say, I want to just read Low Signal initially. 306 00:29:11,000 --> 00:29:15,000 So I just connect low with all the LEDs. 307 00:29:15,000 --> 00:29:25,000 So when I hit on run button, all the LEDs are initially in low state if you want to make it high. 308 00:29:25,000 --> 00:29:34,000 So right now I just remove port zero and connect it to my high signal. 309 00:29:34,000 --> 00:29:36,000 As you see, line zero goes high. 310 00:29:36,000 --> 00:29:43,000 Now line one, it is high, line two, it is high. 311 00:29:43,000 --> 00:29:46,000 And now line four again. 312 00:29:46,000 --> 00:29:47,000 It is also high. 313 00:29:47,000 --> 00:29:55,000 If you change again now connect to ground if you want to change this one also. 314 00:29:56,000 --> 00:30:02,000 So this is how you can generate different signals over your 315 00:30:05,000 --> 00:30:13,000 USB 6009 because now all the LEDs are in low. 316 00:30:13,000 --> 00:30:23,000 This indicates that the signal at the output port is low when it is high or when signal is high at the 317 00:30:23,000 --> 00:30:27,000 output port, it will read the signal and LEDs goes high. 318 00:30:27,000 --> 00:30:36,000 So this is how you can read multiple digital signals using any USB 6009 DAC card. 319 00:30:38,000 --> 00:30:38,000 Thank you. 320 00:31:08,000 --> 00:31:09,000 Today. 321 00:31:09,000 --> 00:31:18,000 I will tell you how to read multiple analog signals using an USB DAC card for that purpose. 322 00:31:18,000 --> 00:31:22,000 I just use multiple signals, as you see over here. 323 00:31:22,000 --> 00:31:34,000 White one is my 2.5V and blue one is my five volt over here on this part, as you see, I have analog 324 00:31:34,000 --> 00:31:38,000 eight analog pins from I zero to I seven. 325 00:31:39,000 --> 00:31:41,000 I stands for analog input. 326 00:31:41,000 --> 00:31:43,000 I, I am just using a zero. 327 00:31:43,000 --> 00:31:47,000 I am using differential mode over here. 328 00:31:47,000 --> 00:31:50,000 So I just this one ground. 329 00:31:51,000 --> 00:31:58,000 So I just make it ground connect to the breadboard orange one is my I four. 330 00:31:59,000 --> 00:32:08,000 So in the case of differential mode, you have to just ground it and yellow one is my I signal I zero 331 00:32:08,000 --> 00:32:13,000 signal and red one is my I one signal. 332 00:32:14,000 --> 00:32:14,000 Okay. 333 00:32:14,000 --> 00:32:23,000 And this is my I5I just ground it and this is my ground. 334 00:32:24,000 --> 00:32:28,000 So it will read different signals. 335 00:32:28,000 --> 00:32:33,000 So right now I just connect Blue one to my eye zero. 336 00:32:33,000 --> 00:32:38,000 It will show five volt and red one is my air one. 337 00:32:38,000 --> 00:32:40,000 It will show 2.5V. 338 00:32:40,000 --> 00:32:42,000 So now go to the software part. 339 00:32:42,000 --> 00:32:48,000 So over here in this case, I just use previous code. 340 00:32:48,000 --> 00:32:51,000 So over here, just go to the browse. 341 00:32:51,000 --> 00:32:53,000 Select multiple signal. 342 00:32:53,000 --> 00:33:02,000 Right now I zero and I one is selected because on the hardware part, I did that configuration. 343 00:33:03,000 --> 00:33:12,000 So over here, analog single channel in place of single channel, I just use multiple channel single 344 00:33:12,000 --> 00:33:12,000 sample. 345 00:33:15,000 --> 00:33:26,000 So over here I just use to post these reports just visible. 346 00:33:26,000 --> 00:33:30,000 It's digital display again, visible. 347 00:33:30,000 --> 00:33:32,000 It's this digital display. 348 00:33:33,000 --> 00:33:40,000 So over here I have one dimensional array data, so I just use index array. 349 00:33:42,000 --> 00:33:45,000 Connect it over here. 350 00:33:45,000 --> 00:33:46,000 Just put. 351 00:33:48,000 --> 00:33:50,000 You have to separate these two signals. 352 00:33:53,000 --> 00:33:54,000 So just connect it. 353 00:33:55,000 --> 00:33:57,000 Control you will minimize. 354 00:33:57,000 --> 00:33:59,000 So as you see, this is my index array. 355 00:34:00,000 --> 00:34:01,000 Here is my port. 356 00:34:01,000 --> 00:34:03,000 Here is my port two. 357 00:34:03,000 --> 00:34:06,000 So when I hit on run button, I got two values. 358 00:34:06,000 --> 00:34:08,000 One is five volt. 359 00:34:08,000 --> 00:34:10,000 Another one is 2.5. 360 00:34:10,000 --> 00:34:12,000 If I just replace it. 361 00:34:12,000 --> 00:34:19,000 So I just connect five volt to the another one. 362 00:34:19,000 --> 00:34:25,000 So now you just check different voltage over here. 363 00:34:25,000 --> 00:34:34,000 So in one potentiometer or you can say one port will show five volt if you connect both with the five 364 00:34:34,000 --> 00:34:37,000 volt or 2.5. 365 00:34:37,000 --> 00:34:40,000 Right now it is connected 2.5. 366 00:34:41,000 --> 00:34:47,000 And if you connect both these with five volt, it will show five volt. 367 00:34:47,000 --> 00:34:53,000 So this is how you can read multiple analog signals using any USB DAC card. 368 00:34:54,000 --> 00:34:54,000 Thank you. 369 00:35:19,000 --> 00:35:31,000 In this lecture, I will tell you how to generate multiple digital signals using an I USB 6009 DAC card. 370 00:35:31,000 --> 00:35:39,000 For that purpose, I just use already built code that I use in previous video. 371 00:35:39,000 --> 00:35:45,000 So over here you just drag it and browse it. 372 00:35:46,000 --> 00:35:48,000 You just select the PIN numbers. 373 00:35:48,000 --> 00:35:50,000 Right now I just use PIN number zero. 374 00:35:50,000 --> 00:35:52,000 PIN number two and pin number 375 00:35:53,000 --> 00:35:59,000 1409040914092. 376 00:35:59,000 --> 00:36:06,000 Just okay, as you see, it is right now, zero Colon two. 377 00:36:08,000 --> 00:36:11,000 The operation is for digital output. 378 00:36:11,000 --> 00:36:20,000 Over here you have to just single channel, single sample, one dimensional lines. 379 00:36:21,000 --> 00:36:25,000 Okay, so just delete this switch. 380 00:36:25,000 --> 00:36:27,000 Delete this one. 381 00:36:27,000 --> 00:36:28,000 Also control V. 382 00:36:29,000 --> 00:36:40,000 Now I just place three push buttons over here, so it is line zero. 383 00:36:46,000 --> 00:36:53,000 This is my line one and this is my line two. 384 00:36:54,000 --> 00:37:00,000 Okay, so now these are my three inputs. 385 00:37:01,000 --> 00:37:04,000 Now I just want to. 386 00:37:09,000 --> 00:37:15,000 Use these inside my while loop. 387 00:37:15,000 --> 00:37:19,000 So I just increase the size of my while loop. 388 00:37:28,000 --> 00:37:35,000 So I just use build array function to add these three signals. 389 00:37:45,000 --> 00:37:48,000 This is my line to control. 390 00:37:48,000 --> 00:37:51,000 Line two is connected over here. 391 00:37:51,000 --> 00:37:52,000 And this line. 392 00:37:53,000 --> 00:37:56,000 Okay, Now you have to just connect it. 393 00:37:58,000 --> 00:38:00,000 So the program is ready. 394 00:38:00,000 --> 00:38:02,000 This function is built. 395 00:38:02,000 --> 00:38:07,000 So I also make it label enabled. 396 00:38:07,000 --> 00:38:09,000 So that's why. 397 00:38:11,000 --> 00:38:21,000 So that you can check out every component control you. 398 00:38:24,000 --> 00:38:26,000 I just minimize the space of this part 399 00:38:29,000 --> 00:38:33,000 so that it is clearly visible to you. 400 00:38:36,000 --> 00:38:41,000 So now, as you see, this is my simple error handler. 401 00:38:41,000 --> 00:38:43,000 Def max, stop task. 402 00:38:44,000 --> 00:38:47,000 This is my three inputs. 403 00:38:47,000 --> 00:38:49,000 Now go to the hardware. 404 00:38:50,000 --> 00:38:51,000 As you see over here. 405 00:38:51,000 --> 00:38:54,000 This is my USB DAC card. 406 00:38:54,000 --> 00:38:56,000 This is my PIN number. 407 00:38:58,000 --> 00:39:03,000 Port 090 port 140, line 140. 408 00:39:03,000 --> 00:39:04,000 Line two. 409 00:39:04,000 --> 00:39:07,000 These three, my signals. 410 00:39:07,000 --> 00:39:09,000 And this is my ground signal. 411 00:39:10,000 --> 00:39:13,000 So over here, I just connected three LEDs. 412 00:39:14,000 --> 00:39:24,000 You can use resistor in between the between the signal and the positive pin of a Led so that it will 413 00:39:24,000 --> 00:39:25,000 not burn out. 414 00:39:25,000 --> 00:39:32,000 Right now I'm not connecting any resistance, so just hit on run button. 415 00:39:33,000 --> 00:39:38,000 As you see all the LEDs goes low. 416 00:39:38,000 --> 00:39:41,000 So right now I'm clicking on line zero. 417 00:39:42,000 --> 00:39:43,000 Led goes high. 418 00:39:44,000 --> 00:39:46,000 Line one Led goes high. 419 00:39:47,000 --> 00:39:50,000 Line two leading goes high. 420 00:39:50,000 --> 00:39:54,000 So all the LEDs are high in this case. 421 00:39:54,000 --> 00:39:58,000 If you want to close the line one, just click on it. 422 00:39:59,000 --> 00:40:01,000 Right now, only two LEDs goes high. 423 00:40:01,000 --> 00:40:09,000 If you want to turn on only led connected with the line two. 424 00:40:09,000 --> 00:40:12,000 So click over here right now. 425 00:40:12,000 --> 00:40:16,000 Only led connected to the line two is high. 426 00:40:16,000 --> 00:40:27,000 So this is how you can generate multiple digital signals using any USB 6009 DAC. 427 00:40:28,000 --> 00:40:29,000 Thank you. 428 00:40:54,000 --> 00:40:55,000 Hello, friends. 429 00:40:55,000 --> 00:41:01,000 In today's video I will tell you how to interface IR sensor. 430 00:41:01,000 --> 00:41:10,000 IR stands for infrared sensor for creating signal or for acquiring signal. 431 00:41:10,000 --> 00:41:17,000 So we will use IR sensor in different applications like object detection. 432 00:41:17,000 --> 00:41:21,000 As you see here, this is my infrared sensor. 433 00:41:21,000 --> 00:41:23,000 It is a module. 434 00:41:23,000 --> 00:41:28,000 So over here, this is my transmitter and the black one is my receiver. 435 00:41:28,000 --> 00:41:33,000 So in this module we have three pins. 436 00:41:33,000 --> 00:41:37,000 First one is VCC, second one is ground, and third one is output. 437 00:41:37,000 --> 00:41:45,000 You can acquire signal using this IR sensor in two modes analog mode or digital mode. 438 00:41:46,000 --> 00:41:50,000 So right now I'm just using digital mode. 439 00:41:50,000 --> 00:41:57,000 So for that purpose I just use digital pin of port 090. 440 00:41:57,000 --> 00:42:02,000 I just connect it now I just connect the ground. 441 00:42:02,000 --> 00:42:06,000 That is my middle one now I just connect the. 442 00:42:08,000 --> 00:42:11,000 So as you see over here. 443 00:42:12,000 --> 00:42:21,000 So this is my air sensor, so I have to adjust its setting. 444 00:42:24,000 --> 00:42:30,000 When object is there in front of this, it will detect it. 445 00:42:30,000 --> 00:42:34,000 And it shows why this. 446 00:42:35,000 --> 00:42:39,000 As you see right now, my hand is there and it goes high. 447 00:42:40,000 --> 00:42:44,000 Right now I remove my hand when it goes low. 448 00:42:44,000 --> 00:42:46,000 So it will generate signal. 449 00:42:47,000 --> 00:42:49,000 So now go to the software part. 450 00:42:49,000 --> 00:42:55,000 Over here I just use single signal read code. 451 00:42:55,000 --> 00:42:59,000 As you see over here, I just select line zero. 452 00:43:00,000 --> 00:43:03,000 This is my create virtual channel. 453 00:43:03,000 --> 00:43:10,000 And over here I just select digital input, start the task, read the task because this sensor will 454 00:43:10,000 --> 00:43:11,000 generate a signal. 455 00:43:12,000 --> 00:43:16,000 And right now I'm just assuming that it is a digital signal. 456 00:43:17,000 --> 00:43:27,000 So I just use single channel, single sample, one line and one Led is connected to it that is known 457 00:43:27,000 --> 00:43:28,000 as sensor. 458 00:43:28,000 --> 00:43:32,000 This is my stop the task and it is my error handler. 459 00:43:32,000 --> 00:43:34,000 So when I hit on run button. 460 00:43:34,000 --> 00:43:44,000 So now LEDs on the IR sensor is also low condition and in my software it is also in low condition. 461 00:43:44,000 --> 00:43:51,000 When I put my hand, it goes red and in my software also it goes high. 462 00:43:51,000 --> 00:43:56,000 So this is how you can acquire signal using IR sensor. 463 00:43:56,000 --> 00:43:58,000 Right now object is detected. 464 00:43:58,000 --> 00:44:03,000 You can use this IR sensor in different applications. 465 00:44:03,000 --> 00:44:12,000 Object detection or door locking, unlocking, checking you can use person's existence. 466 00:44:13,000 --> 00:44:18,000 Okay, so as you see over here, it will acquire signal. 467 00:44:19,000 --> 00:44:24,000 You can adjust its range from this potentiometer over here. 468 00:44:24,000 --> 00:44:26,000 This is rotating potentiometer. 469 00:44:26,000 --> 00:44:32,000 So I just using this, you can increase or decrease this. 470 00:44:32,000 --> 00:44:36,000 The you can increase or decrease the range. 471 00:44:36,000 --> 00:44:42,000 The range of this sensor is low, as you see right now. 472 00:44:43,000 --> 00:44:49,000 If you want to go for higher range, you can just use ultrasonic sensor or laser sensor. 473 00:44:49,000 --> 00:44:57,000 So this is how you can interface IR sensor using an USB 6009. 474 00:44:57,000 --> 00:44:59,000 So this is all for today. 475 00:44:59,000 --> 00:45:00,000 Thank you. 476 00:45:24,000 --> 00:45:25,000 Hello friends. 477 00:45:25,000 --> 00:45:34,000 Today I will tell you how to interface a sound sensor using an a USB DAC card. 478 00:45:34,000 --> 00:45:43,000 So for that purpose it will detect just some sound is available or not. 479 00:45:44,000 --> 00:45:51,000 So as you see over here, this is my sound sensor and this is a module over here. 480 00:45:51,000 --> 00:45:59,000 This is my right one is my pin, middle one is my ground and left one is my VCC. 481 00:45:59,000 --> 00:46:01,000 So I just connect. 482 00:46:01,000 --> 00:46:03,000 So left one is my VCC. 483 00:46:03,000 --> 00:46:06,000 I'll just connect it to VCC then. 484 00:46:06,000 --> 00:46:07,000 Ground pin. 485 00:46:09,000 --> 00:46:11,000 And now over here. 486 00:46:11,000 --> 00:46:12,000 This is my signal. 487 00:46:14,000 --> 00:46:18,000 So right now it is placed over here. 488 00:46:18,000 --> 00:46:23,000 So right now it will detect sound. 489 00:46:23,000 --> 00:46:30,000 You can adjust the sound level if you Now just go to the software part. 490 00:46:30,000 --> 00:46:37,000 Over here, I just create a single channel read signal. 491 00:46:38,000 --> 00:46:41,000 As you see, device 14090 is selected. 492 00:46:42,000 --> 00:46:45,000 Create task digital input. 493 00:46:45,000 --> 00:46:48,000 It will detect the signal based on signal. 494 00:46:48,000 --> 00:46:49,000 Start the task. 495 00:46:49,000 --> 00:46:53,000 This will read sound sensor is connected. 496 00:46:53,000 --> 00:46:55,000 Sound is present or not. 497 00:46:55,000 --> 00:47:01,000 As you see, it is high in this case because it is detecting the sound. 498 00:47:02,000 --> 00:47:05,000 So now over here, please stop the task. 499 00:47:19,000 --> 00:47:19,000 Just. 500 00:47:19,000 --> 00:47:21,000 I'm just checking the signals. 501 00:47:23,000 --> 00:47:24,000 This is my out signal. 502 00:47:26,000 --> 00:47:28,000 So I just adjust. 503 00:47:28,000 --> 00:47:29,000 It's. 504 00:47:31,000 --> 00:47:32,000 Range. 505 00:47:35,000 --> 00:47:37,000 Using this potentiometer. 506 00:47:45,000 --> 00:47:46,000 Hello? 507 00:47:46,000 --> 00:47:47,000 Hello? 508 00:47:48,000 --> 00:47:48,000 Hello. 509 00:47:48,000 --> 00:47:49,000 Hello. 510 00:47:49,000 --> 00:47:51,000 Now it is generating signal. 511 00:47:51,000 --> 00:47:52,000 Hello? 512 00:47:52,000 --> 00:47:53,000 Hello? 513 00:47:53,000 --> 00:47:53,000 Hello. 514 00:47:54,000 --> 00:47:57,000 As you see, it goes high in this case. 515 00:47:58,000 --> 00:48:01,000 So right now just run the code. 516 00:48:06,000 --> 00:48:06,000 Hello. 517 00:48:07,000 --> 00:48:07,000 Hello? 518 00:48:08,000 --> 00:48:08,000 Hello? 519 00:48:16,000 --> 00:48:18,000 So signal is generated. 520 00:48:19,000 --> 00:48:21,000 I just change. 521 00:48:22,000 --> 00:48:23,000 So right now. 522 00:48:24,000 --> 00:48:25,000 Hello. 523 00:48:25,000 --> 00:48:26,000 Hello? 524 00:48:26,000 --> 00:48:27,000 Hello. 525 00:48:27,000 --> 00:48:28,000 It is changing. 526 00:48:28,000 --> 00:48:28,000 Hello. 527 00:48:28,000 --> 00:48:29,000 Hello? 528 00:48:29,000 --> 00:48:30,000 Hello. 529 00:48:30,000 --> 00:48:33,000 So you have to just adjust the settings. 530 00:48:33,000 --> 00:48:35,000 In this case, as you see. 531 00:48:36,000 --> 00:48:39,000 So I just change it. 532 00:48:41,000 --> 00:48:42,000 Hello? 533 00:48:42,000 --> 00:48:43,000 Hello? 534 00:48:43,000 --> 00:48:43,000 Hello? 535 00:48:43,000 --> 00:48:44,000 Hello? 536 00:48:44,000 --> 00:48:44,000 Hello? 537 00:48:52,000 --> 00:48:54,000 So it is in all condition. 538 00:48:55,000 --> 00:48:59,000 Now, as you see, when I goes, my voice goes high. 539 00:48:59,000 --> 00:49:01,000 It will detect the signal. 540 00:49:01,000 --> 00:49:06,000 So this is how you can use sound sensor. 541 00:49:06,000 --> 00:49:17,000 So if you want to check out more in this case, I just make some delay inside this because it is detecting 542 00:49:17,000 --> 00:49:18,000 in milliseconds. 543 00:49:18,000 --> 00:49:25,000 So I just put some 300 milliseconds delay inside this. 544 00:49:25,000 --> 00:49:33,000 So when I hit on run button, as you see now, it is detecting my sound, as you see over here. 545 00:49:35,000 --> 00:49:44,000 So you can put some pressure over here because using pressure, it is detecting the sound and it is 546 00:49:44,000 --> 00:49:48,000 detecting after 300 milliseconds. 547 00:49:48,000 --> 00:49:49,000 Okay. 548 00:49:49,000 --> 00:49:57,000 So this is how you can interface sound sensor using any USB 6009. 549 00:50:02,000 --> 00:50:07,000 As you see, there is a delay of 300 milliseconds in this case. 550 00:50:08,000 --> 00:50:10,000 So this is all about today's lecture. 551 00:50:10,000 --> 00:50:11,000 Thank you. 552 00:50:36,000 --> 00:50:37,000 Hello, friends. 553 00:50:37,000 --> 00:50:50,000 Today I will tell you how to interface a capacitive touch sensor to generate digital signal using an 554 00:50:50,000 --> 00:50:53,000 I USB 6009 DAC card. 555 00:50:53,000 --> 00:51:00,000 So over here, this is my sensor in this this pin left side. 556 00:51:00,000 --> 00:51:02,000 On the right side it is ground. 557 00:51:02,000 --> 00:51:10,000 Middle one is VCC and the right left side it is signal. 558 00:51:10,000 --> 00:51:12,000 So I just connect. 559 00:51:12,000 --> 00:51:14,000 This is my port zero pin. 560 00:51:15,000 --> 00:51:18,000 I just connect it to the signal. 561 00:51:19,000 --> 00:51:25,000 This is black one is my ground, so I just connect it to the ground pin. 562 00:51:26,000 --> 00:51:28,000 So now I just connect. 563 00:51:28,000 --> 00:51:34,000 VCC So this is my middle one is my VCC. 564 00:51:34,000 --> 00:51:38,000 So now it power up the sensor. 565 00:51:39,000 --> 00:51:49,000 So over here, this is my code that is used for single signal read. 566 00:51:49,000 --> 00:51:52,000 So now I am just using port zero. 567 00:51:52,000 --> 00:51:54,000 This is my channel. 568 00:51:54,000 --> 00:51:58,000 Digital input is selected to digital input. 569 00:51:58,000 --> 00:52:02,000 Start the task, read the task as you see over here. 570 00:52:02,000 --> 00:52:05,000 This is my Led for line zero. 571 00:52:05,000 --> 00:52:09,000 This is my stop the task simple error handler. 572 00:52:09,000 --> 00:52:13,000 So when I hit on run button it is in off condition. 573 00:52:13,000 --> 00:52:19,000 So when you touch the sensor, as you see line goes high, line zero goes high. 574 00:52:20,000 --> 00:52:23,000 When I remove my finger, it goes low. 575 00:52:23,000 --> 00:52:31,000 So this is how you can read digital signal from capacitive touch sensor. 576 00:52:31,000 --> 00:52:33,000 So as you see. 577 00:52:34,000 --> 00:52:43,000 So this is how we can acquire digital signal using touch sensor or how you can interface touch sensor 578 00:52:43,000 --> 00:52:48,000 using any USB 6009 card. 579 00:52:49,000 --> 00:52:51,000 So this is all for today. 580 00:52:51,000 --> 00:52:52,000 Thank you. 581 00:53:17,000 --> 00:53:27,000 In the previous video, we just generate three multiple digital signals using USB three 6009 card. 582 00:53:27,000 --> 00:53:36,000 In this video I just make a modification and through this we just create a running light. 583 00:53:37,000 --> 00:53:40,000 So for that purpose, I just use a delay. 584 00:53:40,000 --> 00:53:42,000 This is my time delay. 585 00:53:43,000 --> 00:53:45,000 I just make it visible. 586 00:53:45,000 --> 00:53:46,000 Label. 587 00:53:47,000 --> 00:53:49,000 Wait 100 milliseconds. 588 00:53:50,000 --> 00:53:50,000 Okay. 589 00:53:50,000 --> 00:53:51,000 Over here. 590 00:53:51,000 --> 00:53:54,000 This is my index array. 591 00:53:55,000 --> 00:54:02,000 So I just make it visible label and this is my build array function. 592 00:54:04,000 --> 00:54:08,000 So control u to minimize the space. 593 00:54:08,000 --> 00:54:10,000 So over here, this is my. 594 00:54:13,000 --> 00:54:14,000 Input. 595 00:54:14,000 --> 00:54:19,000 Right now, three inputs are selected line 012. 596 00:54:19,000 --> 00:54:22,000 As you see, zero two, colon two. 597 00:54:22,000 --> 00:54:27,000 Okay, now you have this output. 598 00:54:27,000 --> 00:54:34,000 So the task then over here, I just use an array. 599 00:54:35,000 --> 00:54:37,000 So how you create an array. 600 00:54:37,000 --> 00:54:39,000 So just go over here. 601 00:54:39,000 --> 00:54:40,000 This is my array. 602 00:54:41,000 --> 00:54:44,000 And inside this, you just put push button. 603 00:54:44,000 --> 00:54:47,000 So this is my one dimensional array. 604 00:54:47,000 --> 00:54:50,000 You just make it constant. 605 00:54:51,000 --> 00:54:55,000 And right now, I just use three inputs. 606 00:54:55,000 --> 00:54:58,000 So that's why I select three input over here. 607 00:54:58,000 --> 00:55:01,000 So I just delete this over here. 608 00:55:01,000 --> 00:55:03,000 You just add shift registers. 609 00:55:03,000 --> 00:55:12,000 So just click over here, add shift registers as you see, shift registers are initialized. 610 00:55:12,000 --> 00:55:17,000 Now to initialized created, you have to just initialize it. 611 00:55:17,000 --> 00:55:20,000 So I just remove it. 612 00:55:20,000 --> 00:55:24,000 I just connect this array to my simulator. 613 00:55:24,000 --> 00:55:29,000 Right now, this wire will contain three signals. 614 00:55:30,000 --> 00:55:30,000 Okay. 615 00:55:30,000 --> 00:55:32,000 So I have to split it. 616 00:55:32,000 --> 00:55:36,000 So this is my index array line 012. 617 00:55:36,000 --> 00:55:39,000 Or you can say indexing zero, indexing one, indexing two over here. 618 00:55:39,000 --> 00:55:41,000 These are my three signals. 619 00:55:41,000 --> 00:55:47,000 I just build array for this and connect to my right task. 620 00:55:47,000 --> 00:55:48,000 Okay. 621 00:55:48,000 --> 00:55:51,000 And over here I just use a negate function. 622 00:55:51,000 --> 00:55:55,000 So if the previous value is true, false. 623 00:55:55,000 --> 00:55:55,000 True. 624 00:55:55,000 --> 00:56:01,000 Now, after one loop, the value over here is false. 625 00:56:01,000 --> 00:56:01,000 True. 626 00:56:01,000 --> 00:56:01,000 True. 627 00:56:01,000 --> 00:56:06,000 So right like this way it goes on and on. 628 00:56:06,000 --> 00:56:08,000 So when you hit on run button. 629 00:56:09,000 --> 00:56:17,000 So as you see in the hardware part, hardware is same because line zero is connected to this pin line 630 00:56:17,000 --> 00:56:22,000 one is connected to this pin or this, and line two is connected to this. 631 00:56:23,000 --> 00:56:29,000 So it will go high, low, high, low and you can check it. 632 00:56:30,000 --> 00:56:38,000 So if you want to control the speed, so I'll just stop the task and make it control, create control 633 00:56:39,000 --> 00:56:42,000 and just connect it. 634 00:56:45,000 --> 00:56:46,000 Wait three seconds. 635 00:56:46,000 --> 00:56:48,000 I want to control the speed. 636 00:56:50,000 --> 00:56:53,000 So then I hit on run, as you see. 637 00:56:53,000 --> 00:57:00,000 So if I put 200 over here, so the running speed is slow. 638 00:57:00,000 --> 00:57:13,000 If I put 300 over here now you can check speed and if I put 50 over here, you can check the running 639 00:57:13,000 --> 00:57:15,000 speed of these LEDs. 640 00:57:15,000 --> 00:57:27,000 So this way, in this way you can generate running Led light using any USB 6009 DAC card, or you can 641 00:57:27,000 --> 00:57:35,000 create multiple digital signals using any USB 6009 DAC card. 642 00:57:35,000 --> 00:57:38,000 So this is all for today's lecture. 643 00:57:38,000 --> 00:57:39,000 Thank you.
