Control de Luces LED 220V

flux

El esquema que presentas es un buen punto de partida para un circuito de control de luces LED a 220 V con un microcontrolador de 5 V. Aquí algunos puntos destacados y recomendaciones:
  1. Control de transistores y relés:
    • La salida digital del microcontrolador conecta a través de una resistencia (~1 kΩ) a la base del transistor 2N2222.
    • El colector del transistor se conecta a la bobina del relé SRD-05VDC-SL-C y el emisor a GND.
  2. Protección de picos de tensión:
    • Es correcto incluir un diodo 1N4001 en paralelo con la bobina del relé para evitar que los picos de voltaje dañen el transistor.
  3. Indicador LED:
    • La inclusión de un LED con una resistencia en serie (aprox. 150 Ω) es útil para indicar visualmente la activación del relé.
  4. Manejo de 220 V:
    • Es esencial mantener totalmente separadas las líneas de baja tensión (5 V) y alta tensión (220 V) para garantizar la seguridad eléctrica.
    • Asegúrate de utilizar componentes y aisladores adecuados en la parte de 220 V. Considera incluir dispositivos de protección adicional (fusibles, varistores, etc.).
  5. Buenas prácticas:
    • Probar el circuito en protoboard antes de integrarlo en una PCB es una práctica muy recomendable.
    • Verificar las conexiones de tierra y asegurar un adecuado aislamiento entre las distintas tensiones.
