Round and round and round they go! 16 ultra bright smart LED NeoPixels
are arranged in a circle with 1.75" (44.5mm) outer diameter. The rings
are '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 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 (4-7V works) 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 microconroller 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. Our
wonderfully-written Neopixel library for Arduino 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 16 individually addressable RGB LEDs
assembled and tested.

A light-emitting diode (LED) is a semiconductor light source.LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Introduced as a practical electronic component in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.
