En esta práctica vamos a enchufar los leds como si fueran un semáforo.
Código:
/*
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 led1 = 13;
int led2 = 9;
int led3 = 4;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led1, OUTPUT);
pinMode(led2, OUTPUT);
pinMode(led3, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led1, HIGH); // turn the LED on (HIGH is the voltage level)
digitalWrite(led2, LOW); // turn the LED on (LOW is the voltage level)
digitalWrite(led3, LOW); // turn the LED on (LOW is the voltage level)
delay(1100); // wait for a second
digitalWrite(led1, LOW); // turn the LED off by making the voltage LOW
digitalWrite(led2, HIGH); // turn the LED on (HIGH is the voltage level)
digitalWrite(led3, LOW); // turn the LED off by making the voltage LOW
delay(1100); // wait for a second
digitalWrite(led1, LOW); // turn the LED off by making the voltage LOW
digitalWrite(led2, LOW); // turn the LED off by making the voltage LOW
digitalWrite(led3, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1100); // wait for a second
