Este instructable mostrar cómo he creado una caja de control remoto por un transmisor infrarrojo del TV. He tomado inspiración de este instructable Control cualquier circuito con un TV remoto (y un Arduino). En este enlace pueden descubrir biblioteca le permite decodificar la señal proveniente de su remoto y las instrucciones para descargar e instalar el archivo zip de biblioteca. El objetivo de este proyecto es el reciclaje de antiguos componentes y convertir éstos en módulos electrónicos reutilizables.
