Topic: analogRead() reporting readings in unused pins (Read 557 times) previous topic - next topic


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.
