Hello, I'm trying to make a little desktop excavator arm with 4 servos hooked up to 4 potentiometers. But I can't get the fourth servo to work. I hook three of them up to A0,2,4 and they work. But I can't get the fourth servo to work on pins A1,3,5.
I see there are broken lines on the three "working" pins but I can't find any documentation relating to what those mean. Swapping the wires to working pins shows I have it all wired up correctly and the code is good.
Any help on what those broken lines mean on the OSEPP Uno R3 Plus board mean would be greatly appreciated.
