I’m working on building a WS2811 neopixel Christmas tree controlled just by an Arduino. I’ve seen several of these done using DMX controllers and sequencing software. However, I want to do this only using one (or more) Arduinos. I realize the sequences won’t be as spectacular but I don’t want to buy all the controller hardware and other software to run DMX. I’m thinking of starting out small with something like 6 strings of pixels. I think I should be able to control this many (300) with a single Arduino.
What I’m looking for is an Arduino sketch to use as a starting point. I’ve controlled strings of lights but creating patterns on something shaped like a tree is not something I’ve done. If anyone has any examples or has some sketches they’re willing to share I’m very interested!
