I uploaded the new code and wired the switch to D13 and GND but had no LEDs turn on. I didn't have much time to troubleshoot last night beyond making sure the connections were sound. I also took some voltage readings at the input pin HIGH and LOW states. It was basically 0V at LOW but only 1.8V at HIGH. This seems too low?
How important is the resistor at D13? I had no resistor there once and a 3.9k for a second run with no voltage changes. That was all the time I had yesterday but am hoping to get it working this afternoon. Am I missing something obvious?
Thanks,
Robb
