Así conectas el Módulo relé 12v a un Arduino UNO o ESP32, con un sketch de ejemplo que puedes subir directamente.
Este proyecto demuestra cómo controlar un módulo de relé de 12V con un Arduino Uno. El sketch enciende y apaga periódicamente el relé cada 2 segundos, mostrando el estado actual en el Serial Monitor. Un indicador LED integrado en el módulo se encenderá cuando el relé esté energizado.

Este proyecto muestra cómo controlar un módulo de relé de un solo canal de 12V usando un ESP32. La bobina del relé se alimenta con una fuente de alimentación externa de 12V DC con masa compartida con el ESP32, y GPIO 4 conmuta el relé on y off cada dos segundos.
