could we remove the classes and keep the functions. My code was just the best i could do with the samples of code I got, as long as it works I can do it the way you think is best. I like the functions though as they allow me to change the color real easy and keep my loop simpler. Do you agree. I did not write that classes code it was a old sketch given to me to get my previous regular led model to work, so i tried to use it with the ws2812b model. I almost got it to work.
