Buzzer Module

This piezo Buzzer module is ideally suited to adding noise to your project and is compatible with a pin pitch of 2.54mm while functioning with microcontrollers such as the Arduino. This module lets you respond to programmatic changes with a lovely annoying buzzer that can be altered over a range of frequencies to ensure maximum irritation. To operate the I/O pin must receive a square wave to trigger the buzzer. This can be produced within all popular microcontrollers.
