Documented Code

Arduino Mega 2560 Code

#define LED 6

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

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

This code sets up pin 6 as an output and continuously sets it to HIGH, turning on the LED connected to pin 6.
