Joystick Bricklet

Features

  • 2-axis joystick with push-button

Description

The Joystick Bricklet can be used to extend the features of Bricks by joystick functionality.

The Joystick is two directional and equipped with a push-button. You can read out the position of the stick (X/Y coordinates) and the state of the button. With configurable events it is possible to react on changing positions and an button presses without polling.

You can use this device to control robots, games etc.

Test your Joystick Bricklet

To test a Joystick 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 Joystick Bricklet to a Brick with a Bricklet Cable (see picture below).

Joystick Bricklet connected to Master Brick

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

Joystick Bricklet in Brick Viewer

The tab consists of a coordinate system that shows the current position of the stick and if the button is pressed. Below this coordinate system you can find a graph that visualizes the movements over time. You should be able to reproduce the depicted graph when you move the stick first up, then down, then right and then end left.

If the Brick Viewer does not show "Position (0,0)" when the stick is in center position, press the "Calibrate (0,0)" button.

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

Case

A laser-cut case for the Joystick Bricklet is available.

Case for Joystick Bricklet

The assembly is easiest if you follow the following steps:

  • Screw spacers to the Bricklet,
  • screw bottom plate to bottom spacers,
  • build up side plates,
  • plug side plates into bottom plate and
  • screw top plate to top spacers.

Below you can see an exploded assembly drawing of the Joystick Bricklet case:

Hint: There is a protective film on both sides of the plates, you have to remove it before assembly.
