Oct 16, 2017 · Developing the code was fairly easy, thanks to the availability of arduino libraries from several sources. Without those libraries, this project would have taken a lot longer to put together. Ultimately, I came up with the following code, which works great, although I am still considering it a Beta version. The major component, in addition to Arduino board is the LED light bar. The LED Bar is a prepackaged strip of 3 high-output LEDs powered by 12VDC. Each unit comes with a fully assembled and tested PCB with current limiting resistors, a wall-mount holder and peel-away sticky foam backing, and polarized connection wires. /* Vixen Lights 3.x - Arduino Generic Serial for Addressable Pixels Using this code is pretty straight forward, simply hookup your one wire (WS2811 or WS2812) data line to pin 6 of your Arduino and upload this code. /* 4-8-2011 Spark Fun Electronics 2011 Nathan Seidle This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license). The light controller board takes in serial commands from the main board. When $34# comes in, lights 3 and 4 are turned on. They are turned off after some amount of time.
