Abstract: A control circuit for a joystick includes two dual input NAND gates having one of their inputs connected in common. A potentiometer has a wiper connected to the common NAND gate inputs and has two end terminals each connected to the output of a different NAND gate. A capacitor couples the wiper to ground potential. The control circuit produces a pulsed output signal from one NAND gate when the wiper is moved in one direction from a central position and a pulsed output from the other NAND gate when the wiper is moved in the other direction. The frequency of each NAND output signal varies in relation to the distance that the wiper is moved from the central position.
