This code makes the external LED connected to pin 13

1  int led = 13; // set the "led" variable as 13
2 
3  void setup() {                
4  pinMode(led, OUTPUT);   // designate port 13 as output
5}
6  
7  void loop() {
8  digitalWrite(led, HIGH);   // turn the led on
9  delay(1000);               // wait for 1 second
10  digitalWrite(led, LOW);    // turn the  led off
11  delay(1000);               // wait for a second
12}
