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.
