arduino 24Bit RGB Ring LED WS2812 Light Strip

24Bit RGB Ring LED WS2812 5050 Development Board With Integrated Driver Module There is a single line with a very timing specific protocol to drive the Ring of the LED, Since the protocol is very sensitive to timing, it requires a real time microcontroller such as AVR , PIC, Arduino , mbed etc. NeoPixels LED arranged in a 86mm outside diameter circular PCB. This ring LED's can be simply connected with the microcontroller using only one digital output pin. hence it is possible to control the many RGB LED's using less output pins microcontroller. Each LED lamp is integrated with driver chip in it. so that each LED can be controlled and it becomes addressable. These LED's do not requires and external resistors.
