1 00:00:05,000 --> 00:00:06,000 Hello, friends. 2 00:00:06,000 --> 00:00:17,000 Today I will tell you how to acquire and how to generate C datas using serial communication with the 3 00:00:17,000 --> 00:00:19,000 help of visa in late. 4 00:00:20,000 --> 00:00:30,000 For that purpose I just create the codes as you see over here in my previous videos, as you see over 5 00:00:30,000 --> 00:00:41,000 here in this case I just writing two datas or to write this data over here, I just use a select button 6 00:00:41,000 --> 00:00:51,000 and this select button will send a signal A or D if A is there according to that, it will turn on my 7 00:00:51,000 --> 00:00:54,000 one and this is my two. 8 00:00:54,000 --> 00:01:00,000 And if p signal goes from here, it will turn on led B on the hardware. 9 00:01:00,000 --> 00:01:07,000 As you see over here, I have two elders for input and two LEDs for output. 10 00:01:07,000 --> 00:01:16,000 So this will generate data for my Arduino and Arduino will generate data for these two LEDs. 11 00:01:16,000 --> 00:01:22,000 As you see over here, this one, one green and this one yellow. 12 00:01:22,000 --> 00:01:30,000 And these two LEDs are connected to the PIN number four and five, and the input are connected to eight 13 00:01:30,000 --> 00:01:32,000 and nine digital pin. 14 00:01:32,000 --> 00:01:33,000 Okay. 15 00:01:33,000 --> 00:01:35,000 So just go to the Arduino code. 16 00:01:35,000 --> 00:01:37,000 I will explain you. 17 00:01:37,000 --> 00:01:44,000 So over here I just first configure or assign variable to one led to fifth and fourth. 18 00:01:44,000 --> 00:01:46,000 These are my input pin. 19 00:01:48,000 --> 00:01:49,000 These are my output. 20 00:01:49,000 --> 00:01:51,000 Okay then LDR one. 21 00:01:51,000 --> 00:01:52,000 LDR two. 22 00:01:53,000 --> 00:01:55,000 These are my input pin. 23 00:01:55,000 --> 00:01:57,000 These are from LDR. 24 00:01:57,000 --> 00:02:00,000 Then I have variable. 25 00:02:00,000 --> 00:02:07,000 We are for the output and VR1 and VR2 for input. 26 00:02:07,000 --> 00:02:08,000 Okay. 27 00:02:08,000 --> 00:02:15,000 Then you have to set the pin mode led one led to output LDR one ldr two as a input. 28 00:02:16,000 --> 00:02:18,000 After this, go to the void loop. 29 00:02:19,000 --> 00:02:22,000 I also share this code in my video. 30 00:02:23,000 --> 00:02:34,000 So over here you have to just read serially read the data from the LabVIEW because LabVIEW will generate 31 00:02:34,000 --> 00:02:43,000 a or B signal to turn on Led 1 or 2 or here, if it is equal to A it will turn on Led one. 32 00:02:43,000 --> 00:02:47,000 If it is equal to B, it will turn on led to. 33 00:02:47,000 --> 00:02:50,000 And these are controlled using two different switches. 34 00:02:51,000 --> 00:02:52,000 After this. 35 00:02:52,000 --> 00:02:53,000 Over here. 36 00:02:53,000 --> 00:02:57,000 This is the code for the digital read. 37 00:02:57,000 --> 00:02:59,000 So variable one. 38 00:02:59,000 --> 00:03:08,000 It will read data from LDR one It will read data from LDR two and if variable one is high, it will 39 00:03:08,000 --> 00:03:14,000 send the data to the indexing zero. 40 00:03:14,000 --> 00:03:24,000 See else it will send D and if more character two is high, it will send the character to the indexing 41 00:03:24,000 --> 00:03:33,000 one e otherwise it will send D and just print serial data in line form. 42 00:03:34,000 --> 00:03:43,000 So over here and initially also over here, as you see, I characterize this character as the size of 43 00:03:43,000 --> 00:03:43,000 this. 44 00:03:44,000 --> 00:03:48,000 Or you can say the length of this is to 0 or 1. 45 00:03:48,000 --> 00:03:48,000 Okay? 46 00:03:48,000 --> 00:03:58,000 So you just need to run this code or upload this code into the Arduino board right now. 47 00:03:58,000 --> 00:04:03,000 Arduino The code is uploaded properly. 48 00:04:03,000 --> 00:04:07,000 Now just go to the LabVIEW code over here. 49 00:04:07,000 --> 00:04:11,000 I just combined my two codes. 50 00:04:11,000 --> 00:04:16,000 First one over here it is for Digitalwrite, for the LEDs. 51 00:04:16,000 --> 00:04:23,000 And over here I got the read function from the elders. 52 00:04:23,000 --> 00:04:27,000 Okay, so now you have to just set the comport over here. 53 00:04:27,000 --> 00:04:32,000 So these two will generate signal for different two LEDs. 54 00:04:32,000 --> 00:04:40,000 And over here I got the serial data as you see that is available using visa read over here. 55 00:04:40,000 --> 00:04:42,000 And I just split these signals. 56 00:04:42,000 --> 00:04:46,000 As you see from here, I got zero indexing. 57 00:04:46,000 --> 00:04:53,000 When it is equal to C, it will turn on my Led and when it is equal to E, it will turn on led to that 58 00:04:53,000 --> 00:04:55,000 is available over here. 59 00:04:55,000 --> 00:05:03,000 So right now I just run it as you see right now data is read and I just split it. 60 00:05:03,000 --> 00:05:07,000 So LDR one is off because it is not equal to C LDR two. 61 00:05:07,000 --> 00:05:19,000 It is also because it is not equal to E, So I just place my hand or finger over the LDR so as you see 62 00:05:19,000 --> 00:05:28,000 it will turn on because it is equal to E and when I just put my hand over the LDR one. 63 00:05:30,000 --> 00:05:35,000 It takes some time because it also store the data as you see right now. 64 00:05:35,000 --> 00:05:40,000 So this is how you can read the signals. 65 00:05:40,000 --> 00:05:46,000 And now I just want to upload right data. 66 00:05:46,000 --> 00:05:48,000 So first I turn on this. 67 00:05:48,000 --> 00:05:55,000 As you see Led goes high off it, then turn on this led goes high. 68 00:05:56,000 --> 00:06:00,000 The flickering is because of this time delay. 69 00:06:00,000 --> 00:06:06,000 So this is how if you want to on both the LEDs, this is how you can control. 70 00:06:06,000 --> 00:06:14,000 So this is the code for visa write and read process serially. 71 00:06:14,000 --> 00:06:16,000 So this is all about today's lecture. 72 00:06:16,000 --> 00:06:17,000 Thank you.
