The set up consists of 12 LED poles, 3 LED boxes, and 8 DMX colorblast fixtures. LEDs are mounted behind frosted acrylic to diffuse the light evenly.
Each unit is operating from it’s own dedicated Arduino. At the helm of the Arduinos is an Adafruit FTDI Friend that communicates one way to all 16 at once. Each Arduino has its own internal address and receives 14 byte packets of data telling it what to do (rate, pattern, color, brightness).
All patterns are baked into the Arduino code- that way if there’s ever a serial disconnect, the lights will continue to run. In addition to the pattern data, the computer sends a heartbeat 10 times a second, insuring they stay in sync for patterns like color fading and strobing.
A processing sketch running on the computer controls everything, and is extended further to use an iPad for wireless control via touchOSC and oscP5. We are working on an update for a Lemur sketch to offer even more control.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
