Individually controllable 5050 rgb led strip ws2801

Product Overview:                                                                                                                                                                                                   

An addressable RGB LED strip is a long flexible strand of LEDs each of which can be individually set to a certain color (hence: addressable). By varying the level of red, green and blue (RGB) per LED many color combinations can be made. The chips between the LEDs listen to commands from a controller. This can be an Arduino or other microcontroller or a controller specifically designed for LED strips. 

The WS2801 is a "3-Channel Constant Current LED Driver With Programmable PWM Outputs". It allows you to adjust the brightness of every LED in 256 steps using PWM. A WS2801 chip controls three channels, so you need one chip for every RGB LED. Theoretically this means the WS2801 strips can be cut next to every LED, but I have not seen any strips where this is the case. The chip runs on 3.3-5.5V.
