Thanks to Nathan for sending in the video of his demo box project! He writes:
I had a phone call with an exhibit design company and scheduled an interview. I wanted to build something to bring to the meeting but only had 5 days. The interview got delayed another 3 days, but these
videos show what I achieved in those days incorporating arduino and the neopixel rings from adafruit, along with a variety of other things.
Featured Adafruit Product!
NeoPixel Ring – 16 x WS2812 5050 RGB LED with Integrated Drivers: Round and round and round they go! 16 ultra bright smart LED NeoPixels are arranged in a circle with 1.75″ (44.5mm) 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 (4-7V works) and you’re ready to rock. Read more.
