Add some dazzle to your Spark Core or Photon with this custom-made NeoPixel ring kit! 24 ultra bright smart LED NeoPixels are arranged in a circle with 2.6" (66mm) outer diameter. Snap in your Spark and upload the NeoPixel library code to light up the LEDs, make an Internet of Blinky! 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 about 3.5-5.5 VDC battery pack and you're ready to rock.
To make your project portable, Adafruit have a JST connector for attaching an external battery. Power with 3.5 - 5.5V DC, a rechargeable LiPoly or LiIon cell battery works great, or 3xAAA or 3xAA battery pack. The JST included is so you can make your own battery connection. Use pin D6 for the NeoPixel library code, all other pins are availale to use and have two breakouts on either side so you can wire up other sensors or devices.
Comes as a single round PCB with 24 individually addressable RGB LEDs assembled and tested, two 12 pin 0.1" socket headers and a bonus JST cable. Some light soldering is required, you can solder the two sockets in place to allow unplugging of the Spark, or just solder it directly in place for a slimmer look.

- What Are NeoPixel LEDs?
So in case you haven’t heard yet, digital LEDs are the go-to solution for any project that uses RGB LEDs and you want to avoid the rat's nest that ensures when using multiple RGB LEDs, each colour requiring its own connection. Digital...

Life’s better in colour right? Then why are you still using boring old regular LEDs in your project, when you could be using addressable RGB LEDs. Now LEDS that have Red, Green, and Blue integrated in a single package are nothing new, however t...
