Buzzer Module for Arduino - Active Audible Alert 5V dc motor Install the ESP8266 board packageThe Buzzer Module for Arduino is a 5V active buzzer breakout that beeps on a HIGH signal. No tone() library needed, no frequency math just drive the input pin HIGH and it sounds. LOW = silent. Used for alarms, button feedback, alert tones, countdown timers, and any project that needs an audible signal. Active buzzer = internal oscillator. Drive it with any digital GPIO. Compatible with Arduino, ESP32, Raspberry Pi, and similar boards on 3. 35V logic.
