Analog stick

~ ~ ~ ~ ~ ~ ~ ~ ~ ~

An analog stick, often mistakenly referred to as a joystick, is an input device for a controller, often a game controller, that is used for two-dimensional input. It consists of some sort of protrusion from the controller, and the input is based on the position of this protrusion. While a digital joystick relies on single electrical connections for movement (with contacts for up, down, left and right), an analog stick uses continous electrical activity running through potentiometers. The analog stick has greatly overtaken the D-pad in prominence and usage in console video games.
