Jake,
If you are getting that voltage range on those pins as you adjust the pots it means that the pots are working correctly and giving the microcontroller the proper voltage. So by deduction, we can say that the microcontroller is damaged and not working correctly.
Your microcontroller may be re-flashable, but it may have been damaged enough by static electricity that I can’t guarantee it will work. If you’d like to get a new microcontroller then contact us via email and let us know your serial number: info “at” zeppelindesignlabs “dot” com …we’ll let you know how to get one if that’s what you want to do.
To prevent static electricity damage you need to make sure that you are grounded, and not at a different potential (voltage) difference than the thing you’re handling. In our lab we have ESD conductive wrist bands that keep us “electrically” connected to the AC mains ground. If you don’t have a ESD wrist band then just make sure you are touching something big and conductive (that is grounded) as you touch static sensitive parts to make sure that no voltage difference can build up on either you or the thing you are working on.
Anyway, sorry about the trouble.
Take care,
-Brach
