Ok, I get it pretty much now. Basically, the Robot Controller is a fancy voltmeter hooked up in a parallel to the post-wiper section of the resistor. Just one more question... which end produces a 0 V value and which end produces a 5 V one? I believe the analog input voltage tapers off as I move the wiper from the positive end to the ground... am I correct?
