Quick Overview
This DIYables active piezo buzzer module generates a fixed-frequency tone with simple on/off control from Arduino, ESP32, ESP8266, and Raspberry Pi. Unlike passive buzzers, active buzzers have built-in oscillators that produce sound when powered, requiring only a digital HIGH signal.
The module features convenient mounting holes for secure installation in projects and operates on 3.3V-5V, making it compatible with most microcontrollers. The 3-pin interface (VCC, GND, Signal) provides simple connection to any digital output pin.
Ideal for alarms, alerts, notifications, and simple sound indicators. The active design enables instant sound generation without PWM programming, perfect for straightforward beeping applications in security systems, timers, and status indicators.
