Adafruit NeoPixel Ring - RGB LED w/ Integrated Drivers - 16 pixel arduino Due to its small cuteRound 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
