Dual Button Bricklet


The Dual Button Bricklet is discontinued. We are selling our remaining stock. The Dual Button Bricklet 2.0 is the recommended replacement.


  • Two tactile buttons with built-in blue LEDs
  • LED auto-toggle possible


The Dual Button Bricklet is equipped with two buttons and can extend Bricks. Both buttons have a built-in blue LED. You can read the current state of the button (pressed/released) and of the LED (on/off). You can turn the LED on/off yourself or enable auto-toggle. In auto-toggle mode the LEDs are toggled between on/off with each button press.

It is also possible to use events. This allows to react to button presses without polling.

Test your Dual Button Bricklet

To test a Dual Button 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 Dual Button 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 "Dual Button Bricklet" in the Brick Viewer after a moment. Select this tab. If everything went as expected you can now see button presses and change the state of the LED.
