Re: potentiometer typo?

Voltage dividers will work, but not perfectly. You need to put a series resistance in the ground side to offset the voltage so the OI can read the full range of values from the potentiometer. I think the lower limit of usable voltage into the OI is about 600 millivolts.

I apologize for not being more specific, but I never actually did this. I'm just remembering a discussion from some time last year.
