Así conectas el Módulo de relé 5v Low a un Arduino UNO o ESP32, con un sketch de ejemplo que puedes subir directamente.
Este proyecto muestra cómo controlar un módulo de relé active-low de 5V con un Arduino Uno. El sketch alterna el relé entre ON y OFF cada dos segundos mientras imprime el estado actual en el Serial Monitor. Como se trata de un módulo active-low, poner el pin de control en LOW activa el relé, y ponerlo en HIGH lo desactiva.

Este ejemplo muestra cómo controlar un módulo relé de 5V active-low con el ESP32. La bobina del relé se alimenta desde el pin VIN (5V de USB), mientras GPIO 4 conmuta el pin de control. Poner el pin de control en LOW energiza el relé, y ponerlo en HIGH lo apaga.
