Piezo Buzzer Bricklet


The Piezo Buzzer Bricklet is discontinued and is no longer sold. The Piezo Speaker Bricklet is the recommended replacement.


  • Creates 1kHz beep
  • Configurable beep duration


The Piezo Buzzer Bricklet ca be used to extend the features of Bricks by the capability to beep. The device can output 1kHz beeps in different lengths. It is possible to beep for a specified timespan or to transmit a Morse Code string.

A typical application is to beep on specific events (e.g. "email received").

Test your Piezo Buzzer Bricklet

To test a Piezo Buzzer Bricklet you need to have Brick Daemon and Brick Viewer installed. Brick Daemon acts as a proxy between the USB interface of the Bricks and the API bindings. Brick Viewer connects to Brick Daemon. It helps to figure out basic information about the connected Bricks and Bricklets and allows to test them.

Connect the Piezo Buzzer Bricklet to a Brick with a Bricklet Cable (see picture below).

Piezo Buzzer Bricklet connected to Master Brick

If you connect the Brick to the PC over USB, you should see a new tab named "Piezo Buzzer Bricklet" in the Brick Viewer after a moment. Select this tab. If everything went as expected the Brick Viewer should look as depicted below.
