My Arduino Uno has begun reporting varying analog readings at all times, regardless of whether anything is connected to the pin or not and regardless which pin I check.
Is the Arduino fried? Irreparably?
Thanks for any help.

Ah, thank you so much Coding Badly. I'd forgotten about the internal pull-ups.
