For this assignment I was to make a linear position sensor. I modified the 'Hello 4" board to include an extra header. To the board, I attached one large copper pad, and one small copper pad. It was the distance between the two that I was attempting to measure. I then modified the existing 'Hello 3' code and wrote the necessary code to support the linear position sensor. A simple GUI was then created to display the distance between the two copper pads.

I wanted to add a conceptual theme to this project by placing a doll on each copper pad and measuring the distance between them, however the deadline arrived too quickly for this to be realized.
