Así conectas el Módulo zumbador activo a un Arduino UNO o ESP32, con un sketch de ejemplo que puedes subir directamente.
Este proyecto muestra cómo controlar un módulo active buzzer con un Arduino Uno. El active buzzer genera un tono de frecuencia fija cada vez que el pin de señal se pone en HIGH. El código enciende y apaga repetidamente el buzzer para crear un sencillo patrón de aviso sonoro.
