Arduino NeoPixel library
A library to control one wire protocol RGB and RGBW leds like APA106, SK6812, WS2811, WS2812 and WS2813 that are commonly refered to as NeoPixels and two wire protocol RGB like Lpd8806, APA102 and SK9822 commonly refered to as DotStars. Supports most Arduino platforms.
Please read this best practices link before connecting your NeoPixels, it will save you a lot of time and effort.
Adafruit NeoPixel Best Practices
For bugs, make sure there isn't an active issue and then create one.
Why this library and not FastLED or some other library?
Installing This Library (prefered, you just want to use it)
Open the Library Manager and search for "NeoPixelBus by Makuna" and install
Installing This Library From GitHub (advanced, you want to contribute)
Create a directory in your Arduino\Library folder named "NeoPixelBus"
