The Active Buzzer Module is a simple and easy-to-use sound-generating module designed for alarms, notifications, and user-interface feedback in electronic projects. Unlike passive buzzers, the active buzzer has a built-in oscillating source, which means it only requires a DC supply to produce a consistent sound—no external frequency signal is needed.

Features:

1. Built-in oscillation circuit for direct DC drive.
2. Produces continuous sound when powered.
3. Compatible with Arduino, ESP32, Raspberry Pi, and other controllers.
4. Simple 3-pin interface (VCC, GND, I/O).
5. LED indicator for power/signal status (on some versions).
