Ive had someone else check the circuit and pots and they're fine.
QuoteIve had someone else check the circuit and pots and they're fine.All that means is that they have failed to find the problem.As you see from multiple people this is not the way this circuit behaves.You need to post both a schematic and a good photograph of your setup.
A0 and A2 must be grounded... and that's not all I need to read A0 and A2
I didn't think these were the pins you were reading? I thought you were reading 1 and 3?
but if the order is A0, A1, A2, A3 is read, it absolutely makes sense.
One possibility is that the microcontroller is damaged - has this been ruled out?
Tried it on an Uno and a Mega... Same exact problem on each.
Your observations do not tally with your description of the circuit. So the circuit is not as we understand it from your description.One of the first things I suggest you do is measure your pots with a multimeter and make sure they really are 10K from end to end.
