This is an project example using smart programmable LEDs WS2812. WS2812 is a intelligent control LED light source that the control circuit and RGB chip are integrated in
a package of 5050 components. These LEDs are 24bit programable LEDs (using single wire NZR communication mode as data transfer protocol). In this project 24 LED ring with WS2818 LEDs is used (but can be easily configured for other number of LEDs). WS2812 driver is base on MINI-AT small development with atmega328 microcontroller by Mikroelektronika.

Driver board also utilizes HC-06 bluetooh communication module for wireless control of the LEDs. Sample android application for controling LEDs via bluetooth is design using MIT App Inventor 2.
