Digital I/O

Detailed Description

Usage

1. Call pinMode() to set the pin to OUTPUT, OUTPUT_OPEN_DRAIN, INPUT, INPUT_PULLUP, or INPUT_PULLDOWN
2. Call digitalWrite() with HIGH, LOW or TOGGLE on output pins
3. Call digitalRead() on input pins

Example: Blink

#include <Arduino.h>

// Change to whatever pin an LED is connected to
const int led = PC13;

void setup() {
  pinMode(led, OUTPUT);
}

void loop() {
  digitalWrite(led, TOGGLE);
  delay(1000);
}
