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.
