DFRobot - Gravity: Digital Buzzer for Arduino / ESP32 / micro:bit / Raspberry Pi

This digital buzzer module is a basic breath sound generator that can be driven using a high or low signal. By varying the oscillation frequency, you can hear different sounds. It finds wide application in everyday devices such as personal computers, refrigerators, and mobile phones. With this compact, useful buzzer module, you can also create a variety of intriguing interactive projects.

To simplify the use of this Arduino buzzer module, a Gravity interface is adapted to allow plug&play. The IO expansion shield is the best match for this sound sensor connected to your Arduino. As this sensor can work at 3.3V which makes it compatible with common controllers such as Arduino, micro:bit, ESP32 and Raspberry Pi.

If you are a beginner, it is recommended to purchase an Arduino kit with tutorials, such as the Gravity: Intermediate Kit for Arduino and the Gravity: Starter Kit for Arduino.
