Buenas de nuevo ya estoy trasteando un nuevo proyecto tengo este codigo que poco e ido programando y montando no soy experto en la materia,bueno el tema es que quiero añadir un relé que salte al final del proceso es decir cuando el codigo sea el incorrecto o se acabe el tiempo programado se abra el rele y me de una señal para activar una luz acustica,bien en el pin 10 o 11,pero no se como hacerlo¿se puede modificar el codigo e implantar el relé? o d elo contrario hay que hacer el codigo nuevo entero,el relè seria como este de un solo canal.
Agradesco toda ayuda posible.
codigo:
