The joystick is similar to a game console controller. Each button can be moved in any direction. By pressing the joystick down, an additional button can be used. This way vehicles and robots can be controlled or even own games can be played.
Two signals are received via pins C16 and C17. C16 represents the values of the X-axis and C17 the values of the Y-axis.
