The Arduino LCD HelloWorld example used pins 2, 3, 4, 5, 11, and 12 so those were taken into account when making the IO list reservations. This could have been easily modified in the code, but there was enough room to keep it intact and allowed the example code to be uploaded without modification. Every other screen in this project will have to use modified numbers to send data to the appropriate screen. It was a pleasant surprise when the example code worked immediately since it was assumed that there would need to be some fixes on the hardware. Sometimes it works on the first try.

Potentiometers on the primary module were tested by uploading code that read and printed analog values through the serial terminal. At first, the incoming data was inconsistent and reminded me of why the old hardware was abandoned.

The problem with the hardware turned out to be some missing solder bridges which connected the incoming wires to the outgoing wires on the prototyping board. The same problem occurred on the digital switches. Once these bridges were made, all the inputs worked.
