Description

The piezo electric emits a high-pitch beep that is sure to capture everyone’s attention! To use them, you’ll need to match the wire colors to the wires from the battery pack.

If the volume is too loud, simply use a piece of tape over the top hole on the buzzer and the volume will substantially lower.
