Piezo Speaker Bricklet


The Piezo Speaker Bricklet is discontinued. We are selling our remaining stock. The Piezo Speaker Bricklet 2.0 is the recommended replacement.


  • Creates beeps with configurable frequency of 585Hz to 7100Hz
  • Configurable beep duration
  • Morse code output supported


The Piezo Speaker Bricklet can be used to extend Bricks by the possibility to generate beeps with different frequencies. The available frequency range is 585Hz to 7100Hz. A beep has a configurable length and it is possible to transmit a Morse Code string.

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

Test your Piezo Speaker Bricklet

To test a Piezo Speaker 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 Speaker Bricklet to a Brick with a Bricklet Cable.

If you connect the Brick to the PC over USB, you should see a new tab named "Piezo Speaker Bricklet" in the Brick Viewer after a moment. Select this tab. If everything went as expected you can now generate beeps.

After this test you can go on with writing your own application. See the Programming Interface section for the API of the Piezo Speaker Bricklet and examples in different programming languages.


A laser-cut case for the Piezo Speaker Bricklet is available.
