Arduino Coding Issue...figured I'd ask my peer here first

Just as a suggestion, I'd look at the Pro Micro. Same price, better (small) form factor, USB support is built in,
No need for a shield, just use one for prototyping on a breadboard then solder directly to another board once you are happy with your wired prototype. Just be sure to order the correct voltage for your application (3.3V or 5V).

Only reason I suggest these is because it's so easy to cram it into whatever space you have as it is less than 25% the footprint of an Arduino UNO.
Pretty much everything is going into my bases but I do have one coming for an entirely different project involving a log and some clay.
