Re: [Help!] Analog readings go crazy!
I'm a little late here, but wanted to add my 2 cents anyway.
If your potentiameter is a single-turn(i.e. 210 or 360 degree) pot, then look for damage to the device. If it's a 360 model and turns past it's range, it may make contact with the other side and read the opposite value. We had this happen when our arm went too far in testing. It essentially pushed the pot housing apart a little, letting it spin freely. Resetting it to within it's valid range and tightening the housing down again fixes the issue.
