2022-02-24 (Th) RemoteFinishLine LCD communication

I started to connect the LCD, and I realized that I should have started with this to get alphanumeric feedback without a serial port. Four display terminals needed a ground line, so I soldered a wire jumper. I reconnected the MH-Tiny and shuffled the display's IO declarations to make connecting easy with a bundled cable, so now they all happen in a row. I already had print() statements in the code, so I rerouted them to the new display. My code worked, and I could see text, but only at a steep angle, so I will have to add a potentiometer to adjust the contrast.
It works but the contrast needs work
