My idea is based on 2 potentiometers and one of them is rotated 180 degrees and they are cross connected.
I have tried this setup before and the result of this is an analog output spanning 0-5V if the supply voltage is 5V.
This should work directly with Kasper Skaarhojs Arduino Library for the ATEM Switchers
