i need some info on using the analog outputs as a way of faking a potentiometers function. i am making a head tracker that will interface with an xbox 360 controller to use the head tracking to manipulate the right (head movement) joystick.
as a proof on concept i am controlling the 2 potentiometers in the joystick mechanically using a servo but what i want to do is use the fez domino to fake the potentiometers output. i am assuming that i can wire the analog outputs of the fez to the potentiommeters leads and fake the controller into thinking that i am adjusting the potentometer, but im not really 100% sure of how to occomplish this. anyone have any suggestions or have done anything like this?
