Christmas is near: three WS2812 RGB Rings
Last year a NeoPixel ring with 24 LEDs blinked in our Christmas tree. I presented it on the last MakerFaire Hannover, but unfortunately it was too close to the Tesla coil on our booth, and it stopped working. To be prepared for this year’s Christmas I ordered new rings from Watterott – not one, but three: 16, 24, and 32 LEDs.
