Mini-Project Signal

-I see signals as getting an output when you run a program that can be used to debug code. The best example from my major in Computer Engineering that involves signals would be printing to the Console with print statements. So, for my mini-project I want to use the LCD that came with the Arduino kit to display an output as if it was a Terminal.
-I did project 11 on the Arduino book that came with the kit to familiarize myself with the LCD's library or API.
