A joystick is a computer input device consisting of a stick that can pivot in multiple directions to transmit movement signals to a computer. Most joysticks have two axes of movement like a mouse, while some have three axes to also control twisting. Joysticks are commonly used for games to control in-game movement or actions, and usually have buttons that can trigger commands. Apart from gaming, joysticks are also used to remotely control machines.

1. Introdution:
A joystick is a personal computer peripheral or general
control device consisting of a handheld stick that pivots
about one end and transmits its angle in two or three
dimensions to a computer. Most joysticks are two-
dimensional, having two axes of movement (similar to a
mouse), but three-dimensional joysticks do exist. A
joystick is generally configured so that moving the stick
left or right signals movement along the X axis, and
moving it forward (up) or back (down) signals movement
along the Y axis. In joysticks that are configured for
three-dimensional movement, twisting the stick left
(counter-clockwise) or right (clockwise) signals
movement along the Z axis. These three axis - X Y and Z -
are, in relation to an aircraft, roll, pitch, and
yaw.Joysticks are often used to control games, and
usually have one or more push-buttons whose state can
also be read by the computer. Most I/O interface cards
for PCs have a joystick (game control) port. Joysticks
were popular throughout the mid-1990s for playing the
Descent series and flight-simulators, although they have
declined with the rise of first-person shooters which
instead promote the mouse and keyboard. Modern

2. joysticks (as of 2003) mostly use a USB interface for
connection to the PC. The term joystick has become a
synonym for game controllers that can be connected to
the computer since the computer defines the input as a
"joystick input". Apart for controlling games, joysticks are
also used for controlling machines such as elevators,
cranes, trucks, powered wheelchairs and some zero
turning radius lawn mowers.
