Proyecto Control remoto infrarrojo de 16 canales - Norma RC5 de Philips
El control remoto infrarrojo de 16 canales se basa en el microcontrolador PIC16F73 de Microchip.
La parte del receptor sigue el formato de código RC5 (Philips). El receptor pequeño proporciona 16 salidas contínuas (Latch) u 8 salidas momentáneas + 8 salidas continuas (latch) al cerrar el Jumper J1. Todas las salidas son TTL y pueden controlar relés normales o el relés de estado sólido.
El circuito utiliza el módulo de receptor Infra-Red TSOP1738 que proporciona un alto grado de inmunidad al ruido contra la fuente de luz que pueda ocasionar interferencia.
Caracteristicas del proyecto
El transmisor puede ser cualquier control remoto universal que cumpla la norma RC5 de Philips
El receptor tiene una alimentación de 7V a 12V DC
La frecuencia de modulación es de 38Khz
Rango de operación hasta 6 metros
Indicador LED de funcionamiento
Indicador LED VT (transmisión válida)
Todas las salidas son a Nivel TTL
Jumper (J1) para la selección de modo
J1 Open 16 salidas Latch
J1 Cerrado 8 Salidas Latch + 8 Salidas Momentánea
