  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.

  This example code is in the public domain.

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int ledrojo = 13;
int ledverde=12;
int ledamarillo=11;


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

}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(4000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(4000);               // wait for a second
 
    digitalWrite(ledamarillo, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(4000);               // wait for a second
  digitalWrite(ledamarillo, LOW);    // turn the LED off by making the voltage LOW
  delay(4000);               // wait for a second
 
    digitalWrite(ledverde, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(4000);               // wait for a second
  digitalWrite(ledverde, LOW);    // turn the LED off by making the voltage LOW
  delay(4000);               // wait for a second
