Digital RGB LED strip - 12V, 60 LEDs per meter

5050-sized LEDs with an embedded microcontroller inside the LED. You can set the brightness and color of each R/G/B with 8-bit PWM precision (so 32-bit color per pixel). The LEDs are controlled by shift-registers that are chained up down the strip so you can shorten or lengthen the strip. Only 1 digital output pin are required to send data down. The PWM is built into each LED-chip so once you set the color you can stop talking to the strip and it will continue to PWM all the LEDs for you.
