Can someone explain how to hack a computer touchpad such as this
to function as 2 variable resistors - where resistance #1 is controlled by putting your finger on the x axis, and resistance #2 is controlled by finger on the y axis?
It isn't as simple as finding the right wires to connect to is it? Or has anyone seen a circuit that you can wire a touchpad into and wire your circuit into and achieve this result? Would building such a circuit be hard?
Any info appreciated... thanks
