1pc 24‑Bit WS2812 5050 RGB LED Ring Lamp Light With Integra

Features:
Round and round and round they go! 24 ultra bright smart LED are arranged in a circle with 3.3" (85mm) outer diameter.
The rings are
'chainable' - connect the output pin of one to the input pin of another.
Use only one micro-controller pin to control as many as you can chain
together!
Each LED is addressable as the driver chip is inside the LED.
Each one 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.
There is a single data line
with a very timing-specific protocol.
Since the protocol is very
sensitive to timing, it requires a real-time micro-controller such as an
AVR, PIC, mbed, etc.
It cannot be used with a Linux-based
microcomputer or interpreted micro-controller.
Our wonderfully-written library
supports these 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.
Comes as a single ring with 24 individually addressable RGB LEDs assembled and tested.
