To map all the letter positions, I connected a computer and opened a serial connection. First, I positioned the puck with the potentiometers, and then I recorded the measurements in a text document. I translated the numbers into my Arduino sketch and added a pseudo-random letter selector to point to a new character every five seconds.
For the next step, I added code to recognize incoming serial data and point to the desired letter. At first, it had to be a capital letter, then I added a stipulation to recognize lower-case letters, and lastly, I added the function to go to the numbers. Numbers were the trickiest because, on the ASCII chart, they start at zero and count up to nine, but on my board, they resemble a computer keyboard. I can get to the "HOME" position by sending an exclamation mark.
