Simple Joystick Board
This adds the joystick feature to your Pi project. It was designed with the PSPi in mind, but will work in any project. This does not allow for varying speeds, only full up/down/left/right. You can adjust the resistors to choose what position you want the joystick to enable movement.
Check out the tutorial to see how it works.
