Yes, this is 24 addressable RGB LEDs in a ring, compatible with NeoPixel library. And if you check this video, Rob Zimmerman is happy to program it with Arduino Nano:

 


We have also did a project with the version of 12 LEDs in a ring, just modify the NEOPIXELS to 24 in the program and it is good to be program on the 24 LEDs ring.

Round and round and round they go! 24 ultra-bright smart LED NeoPixels (WS2812B or SK6812) arranged in a circle. Furthermore, the rings are actually 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each color has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're ready to rock. Check out the tutorial by JTronix, instructables. Uses an Arduino Nano to control this type of Ring.


 

SK6812 or WS2812B LED uses a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microcontroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. The wonderfully-written Neopixel library for Arduino from Adafruit supports these LEDs or often being called pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.


It comes as a single ring with 24 individually addressable RGB LEDs assembled and tested.
