1 00:00:00,720 --> 00:00:02,520 Hello, and welcome to this annual lesson. 2 00:00:03,660 --> 00:00:12,390 As usual, the first thing that we do when we start exploring a new hardware is to blink alid or to 3 00:00:12,390 --> 00:00:19,650 write a programming sentence, which is hello first and kiss off our hardware, which is the SPF30 tool. 4 00:00:20,160 --> 00:00:22,860 That example will be led blinking. 5 00:00:23,610 --> 00:00:35,400 So let's go to the examples menu and the Arduino IEEE and open up the sketch example or plink example. 6 00:00:36,300 --> 00:00:36,840 Now. 7 00:00:38,110 --> 00:00:40,360 As you can see, we have a lot of examples here. 8 00:00:41,170 --> 00:00:44,520 You can go to the basics and click Blink. 9 00:00:46,160 --> 00:00:47,540 Now, let's close this window. 10 00:00:48,570 --> 00:00:51,480 Let's open up this one now. 11 00:00:53,000 --> 00:00:58,700 As you can see in this lesson on Discord, that means woman. 12 00:01:00,580 --> 00:01:06,070 We have the lead set to default, which is led number 13 on Arduino. 13 00:01:06,790 --> 00:01:10,120 So we need to change this little number. 14 00:01:10,690 --> 00:01:17,620 As you know, the SB 32 has a built in lid that is connected to its general purpose input output number 15 00:01:17,620 --> 00:01:17,890 two. 16 00:01:18,730 --> 00:01:24,070 It is important to check if Lid Polychain is automatically recognized by IEEE. 17 00:01:24,400 --> 00:01:29,710 If not, you must add to code a line like this light and. 18 00:01:33,300 --> 00:01:44,480 And I cleared it, let's copy it and based it here and now you have to write to to make sure that the 19 00:01:44,490 --> 00:01:55,290 codes will be saved to pin number two, which is the internal lid pin inside the sport. 20 00:01:56,130 --> 00:01:57,780 Now let's save our codes. 21 00:02:04,460 --> 00:02:05,930 Let's leave the name blank. 22 00:02:07,160 --> 00:02:08,539 And let's roll this. 23 00:02:10,740 --> 00:02:16,980 Now, as you can see, it's the very same code that we use, and we have two methods. 24 00:02:17,460 --> 00:02:20,490 The void setup method and the void normally filled. 25 00:02:21,420 --> 00:02:30,180 The Void setup method is basically where you set up things like up in here we have the number two, 26 00:02:30,390 --> 00:02:35,340 which is valid variable and we can replace it with number two here. 27 00:02:35,790 --> 00:02:40,440 But since we are using a variable, we can load the variable name here and here. 28 00:02:40,440 --> 00:02:42,720 We can assign it as input or output. 29 00:02:43,170 --> 00:02:45,930 Since we are dealing with added, it's an output. 30 00:02:45,930 --> 00:02:54,420 So we write output and we use Benmore function to make sure that we set pin number two as output in 31 00:02:54,430 --> 00:02:56,010 the setup loop. 32 00:02:56,430 --> 00:03:03,000 Now, the loop function from its name, it will keep repeating itself. 33 00:03:03,000 --> 00:03:05,760 The loop function runs over and over again forever. 34 00:03:06,990 --> 00:03:11,850 Once you stop the program or stop, turn off the power, it will stop running. 35 00:03:12,420 --> 00:03:21,060 Now the digital right will write a digital value high means one logic or turn on to this pen, which 36 00:03:21,060 --> 00:03:23,960 has been no tool that has internal LED. 37 00:03:24,530 --> 00:03:27,480 Then the delay sentence will wait for a second. 38 00:03:28,080 --> 00:03:31,140 And we will have the same sentence that right? 39 00:03:31,320 --> 00:03:38,190 We will write a digital value which is low or zero or off, and we will wait for another two seconds 40 00:03:38,190 --> 00:03:40,200 so it will turn on valid. 41 00:03:40,860 --> 00:03:45,780 Wait a second, turn it off and wait another second now before. 42 00:03:46,990 --> 00:03:51,760 Uploading this code, we need to go and make sure that we have that do it. 43 00:03:51,850 --> 00:03:58,450 Yes, P32 Dev Kit version one selected and we need to make sure that we have the right compost. 44 00:03:59,380 --> 00:04:01,990 After that, we can simply click Upload. 45 00:04:07,800 --> 00:04:09,000 It will take some time. 46 00:04:09,480 --> 00:04:09,930 OK. 47 00:04:10,560 --> 00:04:14,970 As you can see, you now have an error because this is a system variable. 48 00:04:15,570 --> 00:04:18,990 We can't change it with another name to. 49 00:04:22,770 --> 00:04:23,820 Let's try it again. 50 00:04:41,950 --> 00:04:46,030 As you can see now, it's writing the code done uploading. 51 00:04:47,560 --> 00:04:55,570 Now, if you have the board, you can see that there is a blue LED blinking on and off. 52 00:05:00,770 --> 00:05:01,290 That's it. 53 00:05:01,310 --> 00:05:04,940 This is how simple it is to turn on or off. 54 00:05:05,300 --> 00:05:12,680 And you can use any other pin or connect an external LED if you have one, but that's it for this last 55 00:05:12,680 --> 00:05:12,960 one. 56 00:05:12,980 --> 00:05:16,550 As you can see, it's the very same code that we use and Arduino. 57 00:05:17,360 --> 00:05:18,800 So it's really simple. 58 00:05:19,790 --> 00:05:22,230 It's really easy to get started with this ball. 59 00:05:22,610 --> 00:05:27,710 You don't have a lot of knowledge, just basic knowledge and coding on it and an Arduino. 60 00:05:28,160 --> 00:05:33,620 And if you don't have a basic knowledge, I already explained each line of code inside this sketch. 61 00:05:34,100 --> 00:05:37,970 If you have any question about anything, please ask Invece on the board. 62 00:05:40,320 --> 00:05:41,190 Thanks for watching. 63 00:05:45,540 --> 00:05:47,910 This is Ashraf from educational engineering team.
