I built a game controller with 4 joysticks, meaning there are 8 potentiometers to measure by the nano. It is powered via USB to the computer.
When I deflect one joystick , this affects the position reading of the other sticks, which means that I don't get the resolution I want, and also the center seems to float in the controller app. (vjoyserialfeeder)
I understand that the best solution is to provide independent 5v to each potentiometer, but don't know how to easily do this. (is there a cheap product with a bunch of outputs?)
would it work to just use a beefy 5v supply? Or will that have no effect, as the voltage drop is simply relative anyway.
