So Im building a porch light using some ws2812b's. I am connecting it to openhab so I can do all kinds of fun things based on the time of year, football games and such.
I would like to see if anyone can see in my code, sense I am a beginner, ways to clean it up as what I have already takes up 86% and I would like it to do a few more things. I would really like any feedback, including other things to do with it.
