Dual Button Bricklet 2.0

Features

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

Description

The Dual Button Bricklet 2.0 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.

The Dual Button Bricklet 2.0 has a 7 pole Bricklet connector and is connected to a Brick with a 7p-10p Bricklet cable.

Test your Dual Button Bricklet 2.0

To test a Dual Button Bricklet 2.0 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 2.0 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 2.0" 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.
