Potentiometer issues

We tried moving it to Analog 3, and it still just counts up. incidentally, it exhibits the same behavior when unplugged, and we've tested all possible permutations of pot wiring and gotten the same result.

Nathan,
If you wire the pot so that one outside terminal is connected to five volts and the other outside terminal is connected to zero volts, then the wiper will vary between almost 5 volts and zero volts as the pot moves through it's rotation.

If you really did test all possible permutations of pot wiring, you probably shorted power and ground at some point. I wouldn't be surprised if either the pot or the analog breakout are damaged.

Do you have an electrical mentor who can check your wiring? There's only so much that descriptions from the Internet can help in this situation.
