The joystick apparatus comprises a first potentiometer, a second potentiometer, a bracket interconnected between the shafts of said first and second potentiometers, and a joystick connected to the base of one of the potentiometers. The bracket is interconnected between the shafts of the first and second potentiometers in a manner such that a movement of the joystick along one axis will impart a rotational movement to the shaft of one potentiometer, but will not impart a rotational movement to the shaft of the other potentiometer.Other References
