1 00:00:15,000 --> 00:00:25,000 Eloquence today, I will tell you how to use Blink 2.0 application to control the. 2 00:00:27,000 --> 00:00:38,000 In this video, I also sold our different problems associated with the programming related to Node MCU 3 00:00:38,000 --> 00:00:41,000 and Blink 2.0. 4 00:00:41,000 --> 00:00:50,000 So for that purpose, first, you have to create a count on blink. 5 00:00:52,000 --> 00:00:58,000 Like I just open the platform here. 6 00:00:58,000 --> 00:01:05,000 You have to first create a account or here, just click on Start free. 7 00:01:06,000 --> 00:01:08,000 I already have an account. 8 00:01:08,000 --> 00:01:11,000 I just log in or here. 9 00:01:11,000 --> 00:01:17,000 You can also create a new account when you log in or here. 10 00:01:17,000 --> 00:01:21,000 You have to just click on new template. 11 00:01:22,000 --> 00:01:24,000 Let's say I just use. 12 00:01:27,000 --> 00:01:27,000 Smart. 13 00:01:28,000 --> 00:01:32,000 Or let's see a lady on off. 14 00:01:37,000 --> 00:01:37,000 Okay. 15 00:01:38,000 --> 00:01:38,000 Over here. 16 00:01:39,000 --> 00:01:41,000 You can put any description. 17 00:01:41,000 --> 00:01:46,000 Just done it as you see over here. 18 00:01:46,000 --> 00:01:49,000 We got a lady on off here. 19 00:01:49,000 --> 00:01:50,000 You. 20 00:01:50,000 --> 00:01:57,000 You get all the details related to your hardware and connection. 21 00:01:58,000 --> 00:02:04,000 Then you just go to data stream and blink application. 22 00:02:04,000 --> 00:02:08,000 That is blink 2.0 only. 23 00:02:08,000 --> 00:02:18,000 Virtual pins are available means you have to set what should happen, and you have to read that virtual 24 00:02:18,000 --> 00:02:19,000 pin in your program. 25 00:02:19,000 --> 00:02:22,000 I also show you how we can do that. 26 00:02:23,000 --> 00:02:27,000 So first you have to create new string. 27 00:02:27,000 --> 00:02:29,000 Only virtual pins are there. 28 00:02:30,000 --> 00:02:34,000 So right now over here, you have to name it. 29 00:02:35,000 --> 00:02:37,000 Let's see a lady. 30 00:02:40,000 --> 00:02:41,000 Then over here. 31 00:02:41,000 --> 00:02:42,000 This is my opinion. 32 00:02:42,000 --> 00:02:45,000 Right now PIN number zero is selected. 33 00:02:46,000 --> 00:02:47,000 Zero is selected. 34 00:02:47,000 --> 00:02:48,000 You can select it. 35 00:02:48,000 --> 00:02:50,000 And over here we have data type. 36 00:02:51,000 --> 00:02:56,000 You can use integer double or right now I'm just using integer type. 37 00:02:57,000 --> 00:02:58,000 Just create this. 38 00:02:59,000 --> 00:03:08,000 And as you see, once green is created or you can see one virtual pin is assigned that is visio. 39 00:03:09,000 --> 00:03:17,000 Next, you have to go to your webcast board over here. 40 00:03:17,000 --> 00:03:19,000 You can drag and drop your switch. 41 00:03:20,000 --> 00:03:26,000 Freely available are switch and slider and some display like this. 42 00:03:26,000 --> 00:03:28,000 And over here it is labeled. 43 00:03:29,000 --> 00:03:32,000 And these are freely available. 44 00:03:32,000 --> 00:03:42,000 You can add as number of as which is like over here I see right now. 45 00:03:42,000 --> 00:03:48,000 So I just delete I am just using only one right now. 46 00:03:49,000 --> 00:03:55,000 So in this case, you have to just assign your data stream over here. 47 00:03:56,000 --> 00:03:57,000 Go to settings. 48 00:03:58,000 --> 00:03:59,000 This is my switch. 49 00:04:00,000 --> 00:04:01,000 You can name it. 50 00:04:03,000 --> 00:04:06,000 And over here, this is led with zero. 51 00:04:07,000 --> 00:04:08,000 That is my data stream. 52 00:04:09,000 --> 00:04:16,000 You can also put on and off label over here. 53 00:04:16,000 --> 00:04:21,000 And you can check from here like this. 54 00:04:21,000 --> 00:04:25,000 And you also hide this. 55 00:04:26,000 --> 00:04:28,000 That is your label. 56 00:04:28,000 --> 00:04:30,000 Right now, I just put a zero. 57 00:04:30,000 --> 00:04:35,000 Just saved this part from the dashboard. 58 00:04:36,000 --> 00:04:40,000 Now we just go to our code. 59 00:04:41,000 --> 00:04:44,000 So first I have to save it. 60 00:04:45,000 --> 00:04:45,000 Save? 61 00:04:45,000 --> 00:04:47,000 This is saved. 62 00:04:48,000 --> 00:04:49,000 Now just search. 63 00:04:50,000 --> 00:04:51,000 Go to search. 64 00:04:51,000 --> 00:04:52,000 Over here. 65 00:04:52,000 --> 00:04:56,000 You have to create this form template. 66 00:04:57,000 --> 00:05:00,000 Select the one off that is already created. 67 00:05:01,000 --> 00:05:04,000 Just create as you see. 68 00:05:04,000 --> 00:05:06,000 Or here you got three parts. 69 00:05:06,000 --> 00:05:07,000 That is blank. 70 00:05:07,000 --> 00:05:10,000 Template ID link device Name. 71 00:05:11,000 --> 00:05:11,000 Link. 72 00:05:11,000 --> 00:05:13,000 Authentication token. 73 00:05:13,000 --> 00:05:16,000 You require these three in your code. 74 00:05:17,000 --> 00:05:18,000 So just copy this clipboard. 75 00:05:19,000 --> 00:05:20,000 Go to the code. 76 00:05:21,000 --> 00:05:21,000 Over here. 77 00:05:21,000 --> 00:05:23,000 I just copy this. 78 00:05:25,000 --> 00:05:26,000 I just copy this. 79 00:05:26,000 --> 00:05:28,000 Remove the previous one. 80 00:05:30,000 --> 00:05:36,000 So this is from the code or here? 81 00:05:38,000 --> 00:05:40,000 This is from the code. 82 00:05:40,000 --> 00:05:45,000 So I just again, go over here. 83 00:05:45,000 --> 00:05:48,000 This is my load on off. 84 00:05:48,000 --> 00:05:51,000 And when I click on this, I got this dashboard. 85 00:05:51,000 --> 00:06:01,000 So from search, every time, if you want to work with your dashboard, so just go to search and go 86 00:06:01,000 --> 00:06:01,000 over here. 87 00:06:02,000 --> 00:06:04,000 This is my dashboard. 88 00:06:05,000 --> 00:06:06,000 So now. 89 00:06:07,000 --> 00:06:09,000 Just to go through the program. 90 00:06:09,000 --> 00:06:13,000 I just explained this in this program. 91 00:06:13,000 --> 00:06:24,000 This part comes from the dashboard or your project ID then define blink, underscore print serial, 92 00:06:24,000 --> 00:06:35,000 include your SB 826 verify library include blink simply 8266 library over here the authentication code 93 00:06:35,000 --> 00:06:41,000 and this part is your or your verify. 94 00:06:41,000 --> 00:06:44,000 This is your verify login and this is password. 95 00:06:44,000 --> 00:06:49,000 In my case, this is my login and this is my password. 96 00:06:49,000 --> 00:06:53,000 And over here this is the main code. 97 00:06:54,000 --> 00:06:56,000 This part is the main part. 98 00:06:56,000 --> 00:06:59,000 So over here, blink underscore, right. 99 00:06:59,000 --> 00:07:00,000 Virtual pin zero is selected. 100 00:07:01,000 --> 00:07:08,000 And because I'm working with integer value and value, just assign a variable. 101 00:07:08,000 --> 00:07:12,000 Right now, I'll just assign a name value. 102 00:07:12,000 --> 00:07:17,000 And over here it is equal to bottom. 103 00:07:17,000 --> 00:07:18,000 Dot is. 104 00:07:20,000 --> 00:07:21,000 As integer. 105 00:07:23,000 --> 00:07:23,000 Okay. 106 00:07:24,000 --> 00:07:32,000 And then I went, Let's see, really, if you want to check, I'll put on your serial monitor. 107 00:07:32,000 --> 00:07:39,000 Then you can use this or you can remove also just use this. 108 00:07:40,000 --> 00:07:47,000 Then if this value, this variable value that comes from v zero is equal to one. 109 00:07:47,000 --> 00:07:52,000 In that case, they still write own pin number 16. 110 00:07:53,000 --> 00:07:53,000 Hi. 111 00:07:53,000 --> 00:08:02,000 Basically, these these numbers where you can say PIN numbers comes from node MCU. 112 00:08:03,000 --> 00:08:07,000 Node node MCU. 113 00:08:08,000 --> 00:08:11,000 You know, maximum case. 114 00:08:11,000 --> 00:08:23,000 In maximum case, the users confused with these PIN numbers like in every video available on YouTube, 115 00:08:23,000 --> 00:08:29,000 they just use the 765 and the code will create some error. 116 00:08:29,000 --> 00:08:33,000 So over here, as you see, I'm just using 16. 117 00:08:33,000 --> 00:08:39,000 This is the general purpose input output number 4d04d0. 118 00:08:39,000 --> 00:08:49,000 In we have 16 number for D one pin, we have five, number 42, we have four for the three it is zero 119 00:08:49,000 --> 00:08:50,000 and before it is two. 120 00:08:50,000 --> 00:08:55,000 So like this you have to put these numbers inside your code. 121 00:08:55,000 --> 00:09:01,000 So right now I'm just using 616 that is my distal pin zero. 122 00:09:01,000 --> 00:09:12,000 So when value is equal to one it will write high on my 16th pin means they still pin zero. 123 00:09:12,000 --> 00:09:16,000 I just remove it also because it is not needed over here. 124 00:09:16,000 --> 00:09:25,000 Then if value is equal to zero, in that case it will write low on this pin zero. 125 00:09:25,000 --> 00:09:28,000 The number for this zero is 60. 126 00:09:28,000 --> 00:09:33,000 So this is the mean error available in every video. 127 00:09:34,000 --> 00:09:43,000 They didn't tell you what we have to assign over here does use D seven, d6b5 and it will create some 128 00:09:43,000 --> 00:09:44,000 error. 129 00:09:44,000 --> 00:09:50,000 And now over here we have will set up serial begin. 130 00:09:52,000 --> 00:09:55,000 This is the board rate for node MCU. 131 00:09:55,000 --> 00:10:02,000 Then blink begin or here authentication ID as ID and password. 132 00:10:02,000 --> 00:10:06,000 Then over here you have to set your pin mode right now. 133 00:10:07,000 --> 00:10:08,000 PIN more. 134 00:10:09,000 --> 00:10:14,000 That is my pin and it is working as a output. 135 00:10:14,000 --> 00:10:16,000 So this is my final code. 136 00:10:17,000 --> 00:10:22,000 Now you connect your node MCU with your PC. 137 00:10:23,000 --> 00:10:26,000 Right now I'm connecting my load MCU. 138 00:10:27,000 --> 00:10:38,000 So you have to when you are working with Node MCU, you have to add Blink Library also to your Arduino 139 00:10:38,000 --> 00:10:39,000 ID. 140 00:10:39,000 --> 00:10:44,000 So I already did that and you have to select your board. 141 00:10:44,000 --> 00:10:57,000 I select my board SB module already over here and you have to select your home port like this. 142 00:10:57,000 --> 00:11:01,000 Then just check and see. 143 00:11:14,000 --> 00:11:19,000 So I was always. 144 00:11:41,000 --> 00:11:42,000 Filing is done. 145 00:11:43,000 --> 00:11:56,000 So just download this code to your node MCU and connect a positive bin to the zero of node MCU and negative 146 00:11:56,000 --> 00:11:59,000 bin to the ground of Node MCU. 147 00:12:06,000 --> 00:12:07,000 Take some time. 148 00:12:13,000 --> 00:12:21,000 As you see right now, it is connecting 7%, 15%, 23%, 30%. 149 00:12:23,000 --> 00:12:25,000 It is 100%. 150 00:12:25,000 --> 00:12:30,000 It will ask me to hard reset your. 151 00:12:33,000 --> 00:12:34,000 Resettlement. 152 00:12:35,000 --> 00:12:36,000 Or the city. 153 00:12:36,000 --> 00:12:37,000 Where is it? 154 00:12:37,000 --> 00:12:47,000 So you just disconnect your node MCU from USB and again connect and also put reset on off. 155 00:12:48,000 --> 00:12:49,000 Once only. 156 00:12:50,000 --> 00:12:53,000 So right now you just go to your. 157 00:12:56,000 --> 00:13:02,000 Blink console and when you own it, Lady Will goes on when you're off it. 158 00:13:02,000 --> 00:13:05,000 Lady Will goes off. 159 00:13:05,000 --> 00:13:07,000 So this is for dashboard part. 160 00:13:08,000 --> 00:13:15,000 For the mobile application, you have to go to your play store and install the link application to your 161 00:13:16,000 --> 00:13:22,000 system and login your credentials. 162 00:13:22,000 --> 00:13:30,000 So over here also you have your own on off app. 163 00:13:30,000 --> 00:13:39,000 In this app, you have to just go to click on your template. 164 00:13:39,000 --> 00:13:46,000 And over here you just have a editing option in this editing option. 165 00:13:46,000 --> 00:13:55,000 Just go to a lady on Off and over here we have a gear option, and on the gear option you have to just 166 00:13:56,000 --> 00:14:05,000 add a button when you add a button to your application. 167 00:14:05,000 --> 00:14:10,000 It demands data stream that is already created. 168 00:14:10,000 --> 00:14:14,000 So select that led v zero data pin. 169 00:14:14,000 --> 00:14:19,000 Just make it in the settings push or switch. 170 00:14:19,000 --> 00:14:21,000 So I just go to switch. 171 00:14:22,000 --> 00:14:24,000 Close this back. 172 00:14:25,000 --> 00:14:31,000 And when I hit on run button from the app as you see. 173 00:14:32,000 --> 00:14:35,000 I just remove the header. 174 00:14:35,000 --> 00:14:44,000 So when I right now I'm controlling it from my mobile phone so you can see it on the dashboard also. 175 00:14:44,000 --> 00:14:47,000 It is on, off, on, off. 176 00:14:47,000 --> 00:14:50,000 And the LED also goes on and off. 177 00:14:51,000 --> 00:14:57,000 So this is forcing the lid if you want to work with multiple panes like. 178 00:14:59,000 --> 00:15:04,000 You want to control multiple relays, multiple switches. 179 00:15:04,000 --> 00:15:15,000 In that case, you have to first go to your amp plate, select this or here you have to create more 180 00:15:16,000 --> 00:15:17,000 data streams. 181 00:15:17,000 --> 00:15:26,000 So I just go to edit over here right now, create new data stream like or here I'll just use virtual 182 00:15:26,000 --> 00:15:26,000 PIN. 183 00:15:26,000 --> 00:15:36,000 In this case, my loved one is there and the pin is as you see, V zero is already used. 184 00:15:36,000 --> 00:15:39,000 I just select the one, just create it. 185 00:15:39,000 --> 00:15:43,000 So over here we have the one data stream. 186 00:15:44,000 --> 00:15:46,000 Go to web dashboard. 187 00:15:46,000 --> 00:15:53,000 Over here you can just select another switch, select data stream for it. 188 00:15:54,000 --> 00:16:00,000 So we already used select v one again, save it. 189 00:16:01,000 --> 00:16:03,000 So over here, this is my second switch. 190 00:16:03,000 --> 00:16:07,000 And in the program you just make two changes. 191 00:16:07,000 --> 00:16:12,000 First, just copy this code from here to here. 192 00:16:15,000 --> 00:16:17,000 And raised it. 193 00:16:17,000 --> 00:16:27,000 Right now we in place of zero we have we won and the value or here the variable we'll use or use. 194 00:16:27,000 --> 00:16:30,000 So I just we'll in place of this. 195 00:16:35,000 --> 00:16:40,000 And the PIN number I'm just using from the node MCU. 196 00:16:40,000 --> 00:16:51,000 Let's see right now for the d04 16 and for the one I just use five over here. 197 00:16:52,000 --> 00:16:56,000 So I just put five over here. 198 00:16:56,000 --> 00:17:06,000 So put Node over here in the second one over here to put five and four here. 199 00:17:06,000 --> 00:17:07,000 Five. 200 00:17:07,000 --> 00:17:15,000 And just add on the node copy place. 201 00:17:18,000 --> 00:17:22,000 As you see here it is five just. 202 00:17:24,000 --> 00:17:34,000 Download the code or burn the code to your node MCU and just connect your led host in another led host 203 00:17:34,000 --> 00:17:36,000 pin to your. 204 00:17:38,000 --> 00:17:39,000 D one. 205 00:17:42,000 --> 00:17:45,000 Because we use the one pin over here. 206 00:17:46,000 --> 00:17:55,000 So when it is done, you can also add on another button to your mobile application. 207 00:17:57,000 --> 00:18:01,000 So I just adding by click on plus button. 208 00:18:01,000 --> 00:18:08,000 And over here also you have to select the data stream that is our. 209 00:18:13,000 --> 00:18:18,000 The one can you read a stream is. 210 00:18:25,000 --> 00:18:27,000 Even right now it is done. 211 00:18:28,000 --> 00:18:29,000 So you have to reset. 212 00:18:32,000 --> 00:18:33,000 You have been. 213 00:18:44,000 --> 00:18:47,000 And when I just own, it will own. 214 00:18:47,000 --> 00:18:51,000 And when I just off it, we off. 215 00:18:52,000 --> 00:18:54,000 So over here we also save it. 216 00:18:55,000 --> 00:18:56,000 Right now it is not saved. 217 00:19:01,000 --> 00:19:05,000 So you have to just select the data stream. 218 00:19:08,000 --> 00:19:12,000 So as you see here, I just go to search. 219 00:19:13,000 --> 00:19:14,000 This is my. 220 00:19:17,000 --> 00:19:19,000 Control or template. 221 00:19:19,000 --> 00:19:24,000 So when I own it, my first lady goes on and I own this. 222 00:19:24,000 --> 00:19:26,000 My second lady goes on. 223 00:19:26,000 --> 00:19:30,000 And right now I'm just controlling from my mobile app. 224 00:19:30,000 --> 00:19:35,000 As you see, it is off, off, on, on. 225 00:19:35,000 --> 00:19:43,000 So this is how you can control multiple LEDs using new Blink application. 226 00:19:43,000 --> 00:19:45,000 That is blink 2.0. 227 00:19:45,000 --> 00:19:49,000 That is all about for this. 228 00:19:49,000 --> 00:19:50,000 Thank you.
