Inspired by the turn signal sweater. It sounded great, except I don’t wear sweaters in summer noon heat, or on cold winter days. Enter suspenders!
I have thought of two major improvements I would like to make, which I included in the tutorial.
I had toyed with the idea of adding sound to it, but that was over-ambitious for the end of the semester.
PS, one improvement I forgot to mention in the tutorial itself was a front-visible light or sound to indicate what command was being executed, since I can’t see the lights when they are on my back, and they have proven to be fickle.
