[float]
=== Description
Write a `HIGH` or a `LOW` value to a digital pin.
=== Descripción
Escribe un valor `HIGH` o `LOW` a un pin digital.

If the pin has been configured as an `OUTPUT` with `pinMode()`, its voltage will be set to the corresponding value: 5V (or 3.3V on 3.3V boards) for `HIGH`, 0V (ground) for `LOW`.
Si el pin ha sido configurado como `OUTPUT` con `pinMode()`, su voltaje se ajustará al valor correspondiente: 5V (o 3.3V en placas de 3.3V) para `HIGH`, 0V (masa) para `LOW`.
[%hardbreaks]

If the pin is configured as an `INPUT`, `digitalWrite()` will enable (`HIGH`) or disable (`LOW`) the internal pullup on the input pin. It is recommended to set the `pinMode()` to `INPUT_PULLUP` to enable the internal pull-up resistor. See the digital pins tutorial for more information.
Si el pin está configurado como `INPUT`, `digitalWrite()` activará (`HIGH`) o desactivará (`LOW`) el pullup interno del pin de entrada. Se recomienda ajustar `pinMode()` a `INPUT_PULLUP` para habilitar la resistencia interna de pull-up. Ver el tutorial de pines digitales para más información.
[%hardbreaks]

If you do not set the `pinMode()` to `OUTPUT`, and connect an LED to a pin, when calling `digitalWrite(HIGH)`, the LED may appear dim. Without explicitly setting `pinMode()`, `digitalWrite()` will have enabled the internal pull-up resistor, which acts like a large current-limiting resistor.
Si no establece el `pinMode()` a `OUTPUT`, y conecta un LED a un pin, al llamar a `digitalWrite(HIGH)`, el LED puede aparecer atenuado. Sin ajustar explícitamente `pinMode()`, `digitalWrite()` habrá habilitado la resistencia interna de pull-up, que actúa como una gran resistencia limitadora de corriente.

[float]
=== Example Code
// Describe what the example code is all about and add relevant code ►►►►► THIS SECTION IS MANDATORY ◄◄◄◄◄
The code makes the digital pin 13 an `OUTPUT` and toggles it by alternating between `HIGH` and `LOW` at one second pace.
=== Código de ejemplo
// Describe en qué consiste el código de ejemplo y añade el código relevante ►►►►► ESTA SECCIÓN ES OBLIGATORIA ◄◄◄◄◄
El código convierte el pin digital 13 en una `OUTPUT` y lo conmuta alternando entre `HIGH` y `LOW` a un ritmo de un segundo.

//[source,arduino]
//[fuente,arduino]
----
void setup()
{
pinMode(13, OUTPUT); // sets the digital pin 13 as output
pinMode(13, OUTPUT); // establece el pin digital 13 como salida
}

void loop()
{
digitalWrite(13, HIGH); // sets the digital pin 13 on
delay(1000); // waits for a second
digitalWrite(13, LOW); // sets the digital pin 13 off
delay(1000); // waits for a second
digitalWrite(13, HIGH); // activa el pin digital 13
delay(1000); // espera un segundo
digitalWrite(13, LOW); // apaga el pin digital 13
delay(1000); // espera un segundo
}

=== Notes and Warnings
The analog input pins can be used as digital pins, referred to as A0, A1, etc.
=== Notas y advertencias
Los pines de entrada analógica pueden utilizarse como pines digitales, denominados A0, A1, etc.
