Thanks. The reason I don’t post the code is students complete the work and submit their files for homework. I do have some code samples in the Google Drive for the course at Gallaugher.com. All of the larger project focused builds have code on GitHub and I do have some copy and paste snippets for things like adding lots of colors from the Adafruit LED animations library bit for these small examples I want my students to type and run the code themselves. The small flubs one might encounter from typos, etc are useful for new coders to encounter since they’ll deal with these forever and can quickly learn when and why they happen so they can deal with probs on their own when they arise. Otherwise, I would offer up all code. Cheers and good luck!
