Just finished assembling my Angular Clock. Boot procedure begins as expected, LED's flash. I can connect using Arduino Serial Monitor, BAUD set to 115,200, I receive the opening message, type any key + enter, receive instructions to set hour meter to 1 using dial on rear, but turning knob does not do anything at all. Also, during boot up, meters never deflect to full scale as the instructions say they should. Meters are soundly connected to plug, but there is no indication of meter polarity. Did my best to match pictures in assembly manual. How can I be sure they are properly connected? Any other suggestions?
