2023-02-13 (M) EWC_Box Equipment testing day 1

I added an Arduino Mega to the protoshield mounted in the enclosure. I intentionally mounted the shield upside-down to be able to remove the microcontroller at will. I immediately lost power and searched for a short. There were two problem areas. The first was a row of solder joints on the shield that contacted the USB connector shell. The second issue was a row of pins that touched a mounting bolt. I removed the unused pins and put tape over the USB port.

The Arduino powered up without a problem, and I uploaded the encoder sketch after changing the pin assignments. I had trouble incrementing and decrementing, but I discovered I was using an old copy of the program. Once I put in the latest revision, I mapped the encoders, and everything worked well.
The encoders and Arduino were working
