KY-012 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.
consisting of an active piezoelectric buzzer, it generates a sound of aproximately 2.5kHz when signal is high with a working current of <25mA.
To operate the IN pin must receive a voltage to trigger the buzzer this can be produced within all popular micro controllers.
