1 00:00:01,030 --> 00:00:01,900 Hello and welcome. 2 00:00:01,930 --> 00:00:08,500 This new lesson in what are going to start coding using Arduino IEEE. 3 00:00:12,040 --> 00:00:12,790 No idea. 4 00:00:22,140 --> 00:00:22,590 Now. 5 00:00:31,400 --> 00:00:35,840 Now we will start by including some libraries. 6 00:00:35,930 --> 00:00:41,600 First, we know for sure that we will need let me increase the font size. 7 00:00:42,320 --> 00:00:44,400 We will need the life.I library. 8 00:00:45,110 --> 00:00:48,020 So right, why file the text? 9 00:00:49,130 --> 00:00:51,860 And we also need the Wi-Fi client library. 10 00:00:59,850 --> 00:01:04,980 The techs and we will need that the Adjetey Central Library. 11 00:01:05,610 --> 00:01:07,020 So we have to include it. 12 00:01:15,110 --> 00:01:18,420 And we need blinked. 13 00:01:18,890 --> 00:01:20,480 Yes, P32 Library. 14 00:01:21,590 --> 00:01:23,930 So let's include that, too. 15 00:01:29,570 --> 00:01:29,990 Flanked. 16 00:01:32,640 --> 00:01:36,780 Symbol, yes, but as a tool, the attacks. 17 00:01:39,030 --> 00:01:42,630 Now, these are the main levers that we need. 18 00:01:43,590 --> 00:01:48,600 Let's define some variables, and if we need more labels, we will add them as we go. 19 00:01:49,200 --> 00:01:50,060 And according. 20 00:01:51,450 --> 00:01:55,290 Now define the Ich bin. 21 00:01:57,430 --> 00:02:02,050 And define the the edge. 22 00:02:03,120 --> 00:02:06,420 D-type so let's define again. 23 00:02:09,870 --> 00:02:14,160 The edge type since of type. 24 00:02:15,060 --> 00:02:24,990 Now the sensor type is DHT 11 and the pin, as we already mentioned in the text document, that that 25 00:02:24,990 --> 00:02:27,420 each PIN is number 23. 26 00:02:28,650 --> 00:02:30,390 So here we are, right 23. 27 00:02:31,950 --> 00:02:37,680 Now we need to initialize some variables for the relay. 28 00:02:41,070 --> 00:02:46,830 And other components that we have in the system now, we know for sure that that really is connected 29 00:02:46,830 --> 00:02:49,080 to PIN number 22. 30 00:02:52,450 --> 00:02:53,620 And we also know. 31 00:02:55,470 --> 00:02:57,480 That the water. 32 00:02:59,770 --> 00:03:02,910 The level is connected to Ben. 33 00:03:03,150 --> 00:03:05,720 No, he is 21. 34 00:03:08,540 --> 00:03:19,250 And we will define either variable for that soil sensor, and it's connected to a pin number 19. 35 00:03:24,560 --> 00:03:30,740 Now, just right since we're here and right, since we're here to make sure that. 36 00:03:32,820 --> 00:03:37,290 Now, let's define 24 variables, what the water level. 37 00:03:40,250 --> 00:03:45,770 And the other one, all the soil since. 38 00:03:48,430 --> 00:03:49,160 Live in that. 39 00:03:52,050 --> 00:03:59,070 Now we will use the ADHD library, but let's first save our code. 40 00:04:01,760 --> 00:04:06,470 Now that you have saved the court, let's verify and make sure that we don't have any errors. 41 00:04:06,950 --> 00:04:09,440 We will most likely face a library in error. 42 00:04:09,830 --> 00:04:16,940 As you can see now, the DST library is not recognized, so you need to go to the tools. 43 00:04:17,540 --> 00:04:24,800 OK now include library and from sketch include library manage libraries. 44 00:04:27,040 --> 00:04:30,460 And we need to include these libraries now. 45 00:04:35,030 --> 00:04:37,070 Look for the first library. 46 00:04:38,840 --> 00:04:39,830 The DST. 47 00:04:41,650 --> 00:04:44,740 Library, as you can see here, we have this sense of library. 48 00:04:45,430 --> 00:04:46,480 Click Install. 49 00:04:48,470 --> 00:04:49,490 And it's still all. 50 00:04:55,760 --> 00:04:58,370 Now, as you can see, that number is installed. 51 00:04:59,510 --> 00:05:01,700 Click close, click Verify. 52 00:05:02,300 --> 00:05:11,180 Now you can see that the DHT is recognized, now we have this library playing symbol ESP and good sketch 53 00:05:11,180 --> 00:05:17,150 include library managed libraries and do the same thing to include this library. 54 00:05:22,510 --> 00:05:27,190 Now based right here at the Inter baton. 55 00:05:29,110 --> 00:05:29,890 And wait. 56 00:05:36,400 --> 00:05:41,740 Now you might need to change the key word that you are using to look for the library. 57 00:05:42,340 --> 00:05:48,130 Here we have the blank library and those list has support for SB 32. 58 00:05:49,510 --> 00:05:52,720 And political people all. 59 00:06:02,060 --> 00:06:04,400 Now, as you can see, an installed. 60 00:06:07,110 --> 00:06:12,180 Now click close and try to verify to see if this works or not. 61 00:06:13,200 --> 00:06:19,740 As you can see, Blink Symbol Library is still defined, so we need to read this. 62 00:06:20,700 --> 00:06:25,170 Now, the problem that we have here is that ISP is written in capital letters. 63 00:06:25,200 --> 00:06:28,710 Let's throw a small letter and let's verify. 64 00:06:35,800 --> 00:06:36,150 OK. 65 00:06:36,430 --> 00:06:37,540 Now, as you can see. 66 00:06:42,050 --> 00:06:50,720 This code now recognize that playing library, but since we are choosing Arduino as our pin board, 67 00:06:50,720 --> 00:06:52,700 we are facing a verifying error. 68 00:06:52,880 --> 00:06:59,870 So go and change this to your ISP served 32. 69 00:07:01,780 --> 00:07:02,530 A. 70 00:07:06,080 --> 00:07:08,410 Monoliths look for the one that we have. 71 00:07:09,670 --> 00:07:11,020 Yes, Dev, difficult. 72 00:07:11,920 --> 00:07:12,240 OK. 73 00:07:12,430 --> 00:07:12,890 This one. 74 00:07:13,340 --> 00:07:13,690 Do it. 75 00:07:13,720 --> 00:07:14,940 Yes, we felt it too. 76 00:07:15,460 --> 00:07:21,760 Kept veteran one a little bit before I could see. 77 00:07:23,630 --> 00:07:25,750 That you don't have any unless. 78 00:07:27,240 --> 00:07:31,650 And make sure that you have this and p and small letters here. 79 00:07:46,230 --> 00:07:54,330 It's taking some time, and we have explained how to enable, yes, we have to do when you are doing 80 00:07:54,330 --> 00:07:58,030 an I.D., you need to check this out if you can't. 81 00:08:02,580 --> 00:08:08,480 As you can see now done compiling, which means that all of us are defined and everything's working 82 00:08:08,480 --> 00:08:12,690 just fine now, we need to make sure. 83 00:08:13,580 --> 00:08:15,230 OK, here we have an issue. 84 00:08:15,860 --> 00:08:22,400 Now we need to make sure that we create a new object from the Adjetey sensor. 85 00:08:23,400 --> 00:08:27,410 It's called DST and will take two variables. 86 00:08:27,800 --> 00:08:31,950 The first one is this one DST pin. 87 00:08:33,590 --> 00:08:36,170 The second one is the type. 88 00:08:38,840 --> 00:08:39,320 Now. 89 00:08:40,390 --> 00:08:42,310 We need to add a time of. 90 00:08:43,900 --> 00:08:44,320 This. 91 00:08:45,860 --> 00:08:49,340 Create a new blank document for the blank. 92 00:08:49,760 --> 00:08:53,060 And we will explain why we are doing this later. 93 00:08:55,040 --> 00:08:55,520 Now. 94 00:08:57,650 --> 00:09:00,420 Double check before moving on. 95 00:09:00,440 --> 00:09:10,640 We need to know that for blink up to recognize our ISP world, we need to have an authentication key 96 00:09:11,060 --> 00:09:14,890 which will be provided by the blink once we set it up. 97 00:09:15,350 --> 00:09:16,670 Incoming lessons. 98 00:09:17,090 --> 00:09:20,930 So for now, we need to define a character for that authentication. 99 00:09:23,150 --> 00:09:24,740 And here you need to enter. 100 00:09:26,020 --> 00:09:27,880 Your syndication? 101 00:09:29,700 --> 00:09:30,090 Court. 102 00:09:32,720 --> 00:09:33,170 Now. 103 00:09:35,380 --> 00:09:40,900 Since our ISP board is using Wi-Fi to connect to the internet, we need to make sure that we have the 104 00:09:40,900 --> 00:09:49,360 Wi-Fi sitting set up correctly, so define a new character for the network name. 105 00:09:50,560 --> 00:09:53,140 And here we will add Wi-Fi. 106 00:09:54,650 --> 00:09:55,240 This is. 107 00:09:57,440 --> 00:10:00,980 And another character for the password. 108 00:10:08,770 --> 00:10:12,520 Here's why fi password. 109 00:10:16,640 --> 00:10:19,820 You need to circle on the end of these two lines. 110 00:10:20,570 --> 00:10:28,340 Now we need to create a new method to send our sense of data to the blink up. 111 00:10:29,600 --> 00:10:37,850 Now we know for sure that we have like three or four sensors the alert will call for. 112 00:10:37,850 --> 00:10:39,590 This is pretty straightforward. 113 00:10:40,550 --> 00:10:48,560 We will use that DST sensor library to get that temperature and humidity readings and the water and 114 00:10:48,560 --> 00:10:54,770 soil moisture levels are just analog readings, so we can use the analog function to read the incoming 115 00:10:54,770 --> 00:10:59,060 data and arrange to convert it and send it to our app. 116 00:11:00,620 --> 00:11:07,730 Depending on your environment and sensor constraints, the analog values from the water and soil moisture 117 00:11:07,910 --> 00:11:13,130 levels in soils can be treated and moved into orange. 118 00:11:13,940 --> 00:11:17,810 Now we will create two functions to send data to the blink. 119 00:11:18,170 --> 00:11:24,500 The first function will help send the temperature and humidity values since we are relying on the the 120 00:11:24,500 --> 00:11:26,060 image library. 121 00:11:26,600 --> 00:11:34,730 And the second method will send the water and soil moisture levels, sensors, readings which are basically 122 00:11:34,730 --> 00:11:35,720 analog readings. 123 00:11:36,530 --> 00:11:39,680 It will send these readings to the lab link up. 124 00:11:39,950 --> 00:11:44,060 So let's get started with the first function by void. 125 00:11:48,480 --> 00:11:49,170 Send. 126 00:11:51,070 --> 00:11:52,390 Or ditch. 127 00:11:54,240 --> 00:11:54,750 Now. 128 00:11:56,530 --> 00:12:00,640 This is the first method, and let's define the second method. 129 00:12:00,850 --> 00:12:08,980 Then we can start, I think, both sand and salt water soil. 130 00:12:13,540 --> 00:12:21,100 OK, now we have these two methods and the next lesson, we are going to call these two methods and 131 00:12:21,100 --> 00:12:24,280 proceed with Volley Globe and also that functions. 132 00:12:24,730 --> 00:12:26,140 But that's it for this lesson. 133 00:12:26,170 --> 00:12:28,340 Let's do a quick revision. 134 00:12:28,360 --> 00:12:34,990 We included the Wi-Fi and Wi-Fi client libraries for the Wi-Fi connection, the DST library for that 135 00:12:34,990 --> 00:12:42,220 temperature and humidity sensor that blinks and ISP library so that we can easily connect our ISP filter 136 00:12:42,220 --> 00:12:45,370 to a board with the Blink servers. 137 00:12:46,540 --> 00:12:56,620 We defined these to make sure that we have the correct pin number for the edge sense or tele water and 138 00:12:56,620 --> 00:12:57,580 soil sensor. 139 00:12:58,240 --> 00:13:05,050 And we created two variables to store the incoming data from the water and soil sensor. 140 00:13:05,350 --> 00:13:15,850 Since there are analog readings, we also defined an object called DST from the DHT library and we created 141 00:13:15,850 --> 00:13:24,350 a timer using the Blink Timer Library and the Blink symbol SPF 32 library. 142 00:13:24,970 --> 00:13:27,700 And we will use it at our functions. 143 00:13:28,000 --> 00:13:34,510 Now, will it be mentioned that the Blink has an authentication key for each user and for each? 144 00:13:34,900 --> 00:13:40,960 So you need to intelligent authentication key here, and we will explain how to get it in the practical 145 00:13:40,970 --> 00:13:43,440 lesson regarding the Blink app. 146 00:13:44,200 --> 00:13:51,610 We already mentioned that we are using Wi-Fi connection, so we defined two variables one for the Wi-Fi 147 00:13:51,610 --> 00:13:55,090 network name and the other one for the password. 148 00:13:55,750 --> 00:13:59,060 Now we have two functions. 149 00:13:59,080 --> 00:14:04,060 The first one will be coded to send the temperature and humidity sensor readings. 150 00:14:04,570 --> 00:14:12,190 And the second one will be recorded to send the water and soil moisture level readings. 151 00:14:13,120 --> 00:14:14,320 That's it for this lesson. 152 00:14:14,620 --> 00:14:15,370 Thanks for watching. 153 00:14:15,400 --> 00:14:18,460 If you have any questions, please ask in the Q&A board. 154 00:14:19,030 --> 00:14:21,790 This is Ashraf from educational engineering team.
