Piezo Buzzers

piezo buzzer

Overview

Piezo buzzers are used for making beeps, tones and alerts. The once we have in hackSpace are little but loud! Drive it with 3-30V peak-to-peak square waves. To use, connect one pin to ground (either one) and the other pin to a square wave out from a timer or microcontroller. For the loudest tones, stay around 4 KHz, but they do work quite well from 2KHz to 10KHz.

Wiring the buzzer is very simple you only have a positive and negative. The positive would be connected to one of the digital pins on your Arduino, the tone values will be transmitted though the buzzer.
