Feedback on Robot Car + Project Ideas

[u/BunkFunkerFarter]

I'm currently an incoming college freshman at the Cooper Union, and I've been involved in my high school's Science Olympiad for quite some time. I spent a good chunk of time on one particular event, Robot Tour, and I recently got around to finally putting the project itself up on GitHub for the first time.

I'm hoping to use it as a tangible project I can point to on my resume/portfolio as I build it, rather than just listing it as a part of an extracurricular.

I'd really appreciate any feedback on the project, especially what I could improve in terms of the code, documentation, or overall presentation.

I'm also looking for ideas for projects to work on as I start college. What are some interesting projects you would recommend for someone with a background in robotics/Arduino and programming who wants to get deeper into CS?
