I'm working on building a WS2811 neopixel Christmas tree controlled just by an Arduino.

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!

Thanks!

@Alex_Tatistcheff - Check out @Jason_Coon 's amazing Tree - V2 at:

He includes the code along with the build details. Also, use the search community box on the left side of this webpage to find other tree projects.

@Ken_White Thanks, that is almost exactly what I had in mind!

Consider using an ESP8266-based board like the WeMos D1 Mini - only about $3.50 and gives you WiFi control of your lights.

If you use tzapu’s WifiManager, it simplifies making wireless APs/connections: https://github.com/tzapu/WiFiManager

I made this one, the code is sloppy, but it works. if ur interested let me know
