If you’re looking for a simple but effective way to build audio into an Electronics or Arduino project, the KY-012 Active Buzzer Module is a great choice, and is designed to simply produce a single-tone sound when the incoming signal is high. This allows for single-pin operation on an Arduino Board, which is perfect for building a custom alarm or detection system that can send out an audible signal when it receives the electronic high signal from the Arduino controller board.

Typical Applications for the KY-012 Active Buzzer Module:

The KY-012 Active Buzzer Module is relatively simple compared to many of the Electronics Modules on the market, and only requires a high signal from a single pin from a microcontroller to activate. This allows it to be used for an extraordinary number of different projects, such as building an alarm system, a detection unit or just a device that makes a noise when specific parameters are met. It operates on voltages between 3.5V and 5.5V, making it one of the easiest modules to use with an Arduino or similar type of board.
