A joystick is a positioning device. It is used to move the cursor position on a CRT screen. Its function is similar to that of a mouse. A joystick is a stick which has spherical ball at its lower end as well as at its upper end.
The lower spherical ball moves in a socket. The joystick can be moved right to left, forward or backward. The electronic circuitry inside the joystick detects and measures the displacement of the joystick from its cental position. The information is sent to the processor.
