Presently this is just the code required to get an LED to blink on and off. A full explanation will follow.

This is the most simple circuit we can build to demonstrate the digital output capabilities of the Arduino

int led = 13;

void setup() {
  //set the pin of our led to be an output
  pinMode(led, OUTPUT);
}

void loop() {
  digitalWrite(led, HIGH); //turn the LED on
  delay(1000); //wait one second
  digitalWrite(led, LOW); //turn the LED off
  delay(1000); //wait one second
