A Joystick consists of the small vertical lever (i.e. stick) mounted on a base which is used to steer the screen cursor around. Most of the joysticks select screen positions with actual stick movement; others respond to pressure on the stick.
The distance from the center position of the bar to the moving position is proportional to the movement of the cursor on the screen in that direction. A potentiometer is attached to the base of the joystick that measures movement.
