These “Fluffy Little Clouds” costumes (and accompanying cloud/umbrella objects!) just might be the most darling blinky costume to date. What do you think? Shared by Selina and Zeke Koch in the Adafruit Forums:
Here’s a link to the halloween costumes we made for our kids.
They had matching cloud costumes (a trinket, some neopixels/ws2811′s, a super simple rf radio and a USB battery). My wife had an umbrella with neopixels playing raindrop animations. I couldn’t use the trinket since I used 112 lights.
The code for the umbrella uses AdaFruit’s NeoPixel library and is posted here.
