To test a RGB LED 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 RGB LED 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
"RGB LED Button Bricklet" in the Brick Viewer after a moment. Select this tab.
You can now see button presses in the GUI and control the backlight RGB LED.
After this test you can go on with writing your own application.

section for the API of the RGB LED Button Bricklet and examples in different programming
