Paddle

A paddle is a game controller that features a round wheel and one or more fire buttons. The wheel is used to typically control movement of the player or an object along one axis of the video screen. Paddle controllers were the first analog controllers; they died out when "paddle and ball" type games fell out of favor. A variation on the Paddle, the Atari driving controller appeared on the Atari 2600. Designed specifically for the game Indy 500, It was almost identical in operation and design to the regular paddle controller. However, its wheel can be continuously rotated in either direction, and it was missing the extra paddle included on the previous model. Unlike a spinner, friction prevented the wheel from gaining momentum.
