NeoPixel Arc Reactor #WearableWednesday

NeoPixel Arc Reactor from David Bick

A quick arc reactor, built from NeoPixel rings from Adafruit. There’s a 24- and 16-pixel ring, with a 7-pixel jewel in the middle. A Flora is mounted behind the rings (though a Gemma would do), and power comes from a battery pack in my pocket.

Code for the pattern can be found at https://github.com/drybones/NeoPixelA…

NeoPixel Ring – 24 x WS2812 5050 RGB LED with Integrated Drivers: Round and round and round they go! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6″ (66mm) outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock. Read more.
