1
00:00:02,669 --> 00:00:05,549
We are going to create our first program.

2
00:00:06,549 --> 00:00:09,029
For this we are going to create a new circuit.

3
00:00:14,789 --> 00:00:17,510
Let's drag and drop the Arduino one board.

4
00:00:21,969 --> 00:00:22,510
A LED.

5
00:00:26,760 --> 00:00:30,379
And a resistor that we will change its value to 330.

6
00:00:38,390 --> 00:00:40,070
Also we can turn it.

7
00:00:43,890 --> 00:00:46,049
And connect one end of the LED.

8
00:00:49,640 --> 00:00:50,380
To ground.

9
00:00:50,920 --> 00:00:51,340
Negative.

10
00:00:52,520 --> 00:00:56,799
And the other end of the LED to the resistor and pin number 7.

11
00:00:57,179 --> 00:01:14,120
The Arduino board has 14 digital pins, that can be configured as outputs or inputs, and 6 analog pins which are inputs.

12
00:01:18,260 --> 00:01:24,400
In addition the digital pins with the symbol of a wave, can also be used as analog.

13
00:01:27,930 --> 00:01:35,750
In addition we have this pin which is an earth pin, together with these 2 and 2 pins at 3, 3V and 5V.

14
00:01:35,750 --> 00:01:44,170
An Arduino program is made up of two distinct parts.

15
00:01:50,689 --> 00:02:03,290
The first is the void setup, where we must configure the pins we will use, whether outgoing or incoming.

16
00:02:03,870 --> 00:02:21,020
We will use the command pin mode the pin number, followed by the word output or input, depending on whether it is outgoing or incoming.

17
00:02:21,020 --> 00:02:25,599
The second part of the programs is known as

18
00:02:25,599 --> 00:02:29,080
Void loop or loop

19
00:02:29,080 --> 00:02:32,840
This is the area where we will write the commands

20
00:02:32,840 --> 00:02:37,479
That we want the components connected to the Arduino to run

21
00:02:37,479 --> 00:02:40,699
Among the most important orders are

22
00:02:40,699 --> 00:02:47,509
Digital write followed by the pin number and the words

23
00:02:47,509 --> 00:02:52,919
High and low

24
00:02:52,919 --> 00:02:58,599
High indicates that the pin is energized

25
00:02:58,599 --> 00:03:06,139
and low means that the current has been cut off another of the most commonly used commands is

26
00:03:06,139 --> 00:03:16,650
delay followed by the number that representing milliseconds and is used to generate a stop in

27
00:03:16,650 --> 00:03:23,990
the program or to delay the execution of the following instructions in the case that we want

28
00:03:23,990 --> 00:03:31,430
use one of the digital pins in an analog way we will have the command analog write

29
00:03:32,229 --> 00:03:39,750
with the number of the digital pin to be used as analog input followed by a number between 0 and

30
00:03:39,750 --> 00:03:52,629
255 once the circuit has been assembled with the electronic components we are going to write the

31
00:03:52,629 --> 00:03:58,710
programming that will enable us to that this led is switched on and off to do so click on the code

32
00:03:58,710 --> 00:04:04,550
button we move on to text and let's take advantage of this code which is the default code to write

33
00:04:04,550 --> 00:04:24,569
our program we are going to write the led flashing program in the void setup structure we will

34
00:04:24,569 --> 00:04:31,529
configure the pin through which current flows which is number seven in our circuit and in the

35
00:04:31,529 --> 00:04:36,649
void loop we are going to indicate to the program how to turn this pin on and off.

36
00:04:38,649 --> 00:04:45,769
In the digital write, we will write the pin number 7, and write high on the back, this causes current

37
00:04:45,769 --> 00:04:54,810
to flow through that pin. Then we will write delay 1000 milliseconds, for a delay to occur or to wait

38
00:04:54,810 --> 00:05:02,269
and keep that led lit. Now write again digita write. We will stop the current going out so

39
00:05:02,269 --> 00:05:18,339
write pin number 7 and low. Finishing write a delay of 1 second. We test the code. There we have it.

40
00:05:20,279 --> 00:05:25,040
I hope you enjoyed the exercise. See you soon.
