Documented Code

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:
  pinMode(13, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(13, HIGH);
}

This code sets pin 13 of the Arduino UNO as an output and continuously sets it to HIGH, which will turn on the connected LED.
