- Joystick:-
A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are often used to control video games, and usually have one or more push buttons whose state can also be read by the computer. 
Joysticks are also used for controlling machines such as cranes, trucks, under water unmanned vehicles, wheelchairs, surveillance cameras.
