PIC12F675 Dimmer Control

0:54

Project

Sí, el PIC12F675 es perfectamente capaz de usarse como controlador de dimmer. Dependiendo de tu aplicación, hay dos enfoques principales:

Dimmer de LEDs (salida DC)
- Generas una señal PWM con uno de sus pines de E/S (por ejemplo usando un temporizador en modo interrupt).
- Con un transistor o MOSFET conviertes esa PWM en corriente variable sobre el LED.
Dimmer de fase para AC (control de lámparas incandescentes o motores)
- Haces detección de cruce por cero de la CA (con un optoacoplador o comparador).
- Tras un retardo controlado por un temporizador, disparas un triac vía optoacoplador para ajustar el ángulo de conducción.

Para poder avanzar con el diseño, necesito que me digas:

¿Qué tipo de dimmer quieres implementar? ¿LED (DC) o fase de AC?
¿Qué rango de potencia o tensión vas a controlar?

Con esa información te puedo proponer un esquema de componentes y la lógica de firmware.

Generic Capacitor
A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
