Hello,
I'm using the 6 analogue pins of my diecimela as input for 6 pots. Everything works fine but data from pins 2 & 3 move in parallel, as if the pins were hardwired. If I turn the pot on pin 2, then data changes on pin 2 AND 3. Moreover it seems that the data is changed to exponential, despite my pots are all linear. When I disconnect one of the 2 pots, the data shown in serial monitor comes back to linear; but data from pin 2 and data from pin 3 are still identical.
I tried to put delay in the loop, change the pot values, even tried to put a capacitor between the two pins, but noting changes. Are my input broken ??
thanks for the help
Sounds like Pin A2 and Pin A3 might be shorted together. Check your wiring.
thanks for your quick reply,
actualy I checked several times for shorted, even changed the board. Now I only have these 2 pots plugged directly in the pins of the arduino via small flexible cable. And still the same problem...any other idea?
Does a DMM measure different voltages on those pins?
