Adafruit 24 NeoPixel Ring - RGB LED with Integrated Drivers

Round and round and round they go! Ultra bright smart LED NeoPixels arranged in a circle.

• 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.
• Comes as a single ring with 24 individually addressable RGB LEDs assembled and tested.
• 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 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. Adafruits 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. PRODUCT VIDEOS
