For the output devices exercise I decided to experiment using the provided boards and code for the stepper motor and the charlieplexed LED array. The stepper motor board was pretty straight forward. I had trouble programming both boards because I was not powering them at first, but once I figured out that issue, it was smooth sailing.

I had to make the chalieplexing board twice. Initially because of the issue where I was not powering the boards (I thought I was just globally a bad solderer). But then when all was said and done, the first board I made had a bad LED somewhere.

In the end I was able to manipulate the code in a way that let me spell out my initials.

Here is the code that I changed from Neil's original.
