Keyestudio Passive Buzzer Alarm Module for Arduino

The Keyestudio Passive Buzzer Alarm Module is an easy-to-use acoustic component designed for creating sound and music in your microcontroller projects. Operating on a digital interface, it is perfect for South African students, educators, and makers looking to explore audio programming with Arduino. By applying different external frequencies, you can easily code custom melodies, alarms, and interactive sound effects.

Simple acoustic-optic displays

Buzzers provide a simpler, more straightforward alternative to complex speakers for adding audio to your interactive builds. This module allows you to easily incorporate sound feedback into your Arduino experiments.

External frequency control

Unlike active buzzers, this passive buzzer cannot actuate by itself and requires an external pulse frequency to produce sound. By varying the input frequency, you can generate a wide range of distinct tones and pitches.

Code your own melodies

With an Arduino or compatible microcontroller, you can program custom musical notes and sequence them into full songs. This makes it an engaging tool for students learning the basics of frequency modulation and coding.

Broad operating voltage range

The module operates reliably on a working voltage of 3.3V to 5V, making it compatible with a wide variety of development boards. This ensures safe integration with both standard 5V Arduinos and lower-voltage 3.3V systems.

Digital interface integration

Featuring a standard digital interface, the module connects directly to your microcontroller's digital I/O pins. This simplifies wiring and keeps your breadboard or project chassis clean and organised.

Comprehensive learning resources

To help you get started quickly, the module is supported by official wiki tutorials and software guides. These resources provide step-by-step instructions and sample code to accelerate your project development.
