PROYECTO 2 - CONSTRUCCIÓN DE SEMÁFORO PEATONAL A ESCALA

La Srta. Ignacia Martínez, estudiante de la Especialidad de Electricidad, nos entrega un tutorial acerca de cómo implementar un semáforo peatonal a escala en base a Arduino y un módulo de relé de dos canales.
PROGRAMACIÓN:
void setup() {
pinMode (9, OUTPUT); // LED ROJO
pinMode (8, OUTPUT); // LED VERDE
}
void loop() {
digitalWrite (9, LOW); // ENCIENDE LED ROJO
digitalWrite (8, HIGH); // APAGA LED VERDE
delay (10000);
digitalWrite (9, HIGH); // APAGA LED ROJO
digitalWrite (8, LOW ); // ENCIENDE LED VERDE
delay (5000);
digitalWrite (8, HIGH);
delay (500);
digitalWrite (8, LOW);
