FadeCandy - Dithering USB-Controlled
Driver for NeoPixels
PRODUCT ID: 1689
-DESCRIPTION
A new collaboration between Adafruit & Micah from Scanlime, we are excited to
introduce Fadecandy, a NeoPixel driver with built in dithering, that can be
controlled over USB. Fadecandy is not just hardware! It is a kit of both hardware
and software parts that make LED art projects easier to build and better-looking so
sculptors and makers and multimedia artists can concentrate on beautiful things
instead of reinventing the wheel. It's an easy way to get started and an advanced
tool for professionals. It's a collection of simple parts that work well together:
• Firmware that uses unique dithering and color correction algorithms to raise
the bar for quality while getting out of the way of your creativity.
• Open source hardware for connecting cheap and popular WS2811 based LEDs
to a laptop, desktop, or Raspberry Pi over USB.
• Fadecandy Server Software, which communicates with one Fadecandy board or
dozens. It runs on Windows, Linux, and Mac OS, and on embedded platforms like
Raspberry Pi.
• The Open Pixel Control protocol, a simple way of getting pixel data from your
creative tools into the Fadecandy server.
• Libraries and examples for popular languages. We have Python and Processing
already, with Javascript and Max coming soon.
• LEDs! Fadecandy works with Adafruit's popular WS2811/WS2812 LEDs. Each
controller board supports up to 512 LEDs, arranged as 8 strips of 64 each.
Headers are not included but we have tons of different kinds of dual header in the
shop if you want to solder something into the pads.
Fadecandy is designed to enable art that is subtle, interactive, and playful -
exploring the interplay between light, form, and shadow. If you’re tired of seeing
project after project with frenetic blinky rainbow fades, you’ll appreciate how easy
it is to create expressive lighting!
It's also battle tested! The firmware was originally developed to run the Ardent
Mobile Cloud Platform, a Burning Man project which used 2500 LEDs to project
ever-changing rolling cloud patterns onto the interior of a translucent plastic

sculpture. It used five Fadecandy boards, a single Raspberry Pi, and the effects
were written in a mixture of C and Python. The lighting on this project blew people
away, and it made me realize just how much potential there is for creative lighting,
but it takes significant technical drudgery to get beyond frenetic-rainbow-fade into
territory where the lighting can really add to an art piece instead of distracting
from it.
