2022-03-15 (Tu) RemoteFinishLine Bluetooth plugged in

I started translating my Bluetooth module pseudo-code into an Arduino sketch, but I realized that I couldn't simultaneously send data to it and the computer at the same time. I saw four feasible options:
    Option 1: Print feedback to the LCD
    Option 2: Do all the testing on a Mega, which has multiple serial ports
    Option 3: Add a softwareSerial to my project for debugging
    Option 4: Try to get all my feedback through the onboard LED
I made my list in the most practical order and started with the LCD readout. I added a pair of header pins to the BT socket area to use a removable jumper and apply power to the KEY pin or remove it if necessary. I didn't see a response from the module, but I was waiting on a newline or carriage-return character, which may not be forthcoming. Once I figure out how to see the responses, I should complete the Bluetooth handshake quickly.
