WS2812 RGB LEDs are a lot of fun and allow for colorful displays, indicators, lighting, and more. These LED rings are made up of 8 intelligent 5 x 5mm WS2812 LEDs. Each LED has its own integrated driver and is individually controllable. This small board is a chain of 8 individual LEDs, and each board can be chained to create larger displays and lighting effects using a single Digital IO pin!
These LEDs are powered with 5VDC and have integrated drivers so no resistors are required. These do require a real time microcontroller such as an AVR, Arduino, PIC, mbed, ect. They will not work with Linux based micro-computers, Netduinos, or the Basic Stamp.
To use these LEDs: Connect your digital pin to the “DI” pad (data in) on the back of the module and supply power. The FastLED library for Arduino is a great starting point!
