The NeoPixel Stick 8x WS2812 5050 RGB LED with Integrated Drivers is easy to use, requiring 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. Comes with easy to solder 4 Pin Header.
