We are going to create our first program.
00:00:02
For this we are going to create a new circuit.
00:00:06
Let's drag and drop the Arduino one board.
00:00:14
A LED.
00:00:21
And a resistor that we will change its value to 330.
00:00:26
Also we can turn it.
00:00:38
And connect one end of the LED.
00:00:43
To ground.
00:00:49
Negative.
00:00:50
And the other end of the LED to the resistor and pin number 7.
00:00:52
The Arduino board has 14 digital pins, that can be configured as outputs or inputs, and 6 analog pins which are inputs.
00:00:57
In addition the digital pins with the symbol of a wave, can also be used as analog.
00:01:18
In addition we have this pin which is an earth pin, together with these 2 and 2 pins at 3, 3V and 5V.
00:01:27
An Arduino program is made up of two distinct parts.
00:01:35
The first is the void setup, where we must configure the pins we will use, whether outgoing or incoming.
00:01:50
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.
00:02:03
The second part of the programs is known as
00:02:21
Void loop or loop
00:02:25
This is the area where we will write the commands
00:02:29
That we want the components connected to the Arduino to run
00:02:32
Among the most important orders are
00:02:37
Digital write followed by the pin number and the words
00:02:40
High and low
00:02:47
High indicates that the pin is energized
00:02:52
and low means that the current has been cut off another of the most commonly used commands is
00:02:58
delay followed by the number that representing milliseconds and is used to generate a stop in
00:03:06
the program or to delay the execution of the following instructions in the case that we want
00:03:16
use one of the digital pins in an analog way we will have the command analog write
00:03:23
with the number of the digital pin to be used as analog input followed by a number between 0 and
00:03:32
255 once the circuit has been assembled with the electronic components we are going to write the
00:03:39
programming that will enable us to that this led is switched on and off to do so click on the code
00:03:52
button we move on to text and let's take advantage of this code which is the default code to write
00:03:58
our program we are going to write the led flashing program in the void setup structure we will
00:04:04
configure the pin through which current flows which is number seven in our circuit and in the
00:04:24
void loop we are going to indicate to the program how to turn this pin on and off.
00:04:31
In the digital write, we will write the pin number 7, and write high on the back, this causes current
00:04:38
to flow through that pin. Then we will write delay 1000 milliseconds, for a delay to occur or to wait
00:04:45
and keep that led lit. Now write again digita write. We will stop the current going out so
00:04:54
write pin number 7 and low. Finishing write a delay of 1 second. We test the code. There we have it.
00:05:02
I hope you enjoyed the exercise. See you soon.
