Use this Pixel RGB LED Ring to add a ring of light to your projects. Uses just 1 pin for Input and 1 pin for Output to the next LED ring if you'd like to chain multiple together! Just connect PWR to 5V DC, GND to 0V and Data Input to your Arduino or other microcontroller to control the whole ring. Each of the WS2812 RGB LEDs has a chip inside which allows you to control them when chained one after the other.
