Michael Moxley shared with us a custom blinky sign project that he created using Adafruit NeoPixel RGB LED strips:
This is a project I put together last week using an Arduino Uno and digital RGB LEDs strips I bought from you guys. Using the NeoPixel library, I wrote some functions to show off what the LED strips can do. I hope you guys enjoy it.
This is a custom Prodigy Disc sign I made with programmable RGB.
