Got my self a 24Bit LED ring!

Nice toy with 24 pcs. of ws2812b three wire LED.
I hooked it up to my Arduino UNO and loaded it with the default sketch “NeoPixel FUN” that comes with the NeoPixelBus.h library.

Below you can see some videos i made of the result.
at first I used external 5V supply to measure the load current.
afterwards I powered it from laptop usb supply.

Adafuit has a great guide if you would like to play with NeoPixels yourself.
