UPDATE - 10/10/14: This may not work with the Nano.  I've plugged everything in multiple times - the pin outs are both 40mA for the Mega vs the Nano.  It is possible that I've fried the Nano.  One Nano is connecting to the Arduino IDE where the other isn't recognized.  When I'm done debugging that …
