// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
int led2 = 6;
int led3 = 3;

// the setup routine runs once when you press reset:
void setup() {
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);
  pinMode(led2, OUTPUT);
  pinMode(led3, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, LOW);   // turn the LED on (HIGH is the voltage level)
  digitalWrite(led2, LOW);
  digitalWrite(led3, HIGH);
  delay(5000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  digitalWrite(led2, HIGH);
  digitalWrite(led3, LOW);

  delay(5000);               // wait for a second
