/*
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
