BlinkM Smart LED Uses an ultra-bright wide-angle RGB LED attached to a microcontroller and BlinkM Sequencer — software that fuses a color picker with a drum machine — you program BlinkM to be any color, and blink and fade in virtually any pattern. When you've programmed your BlinkM, you unplug it and pop it into your project. Apply 5 volts, and it does its thing, whether that's glowing your favorite pinkish purple, or pulsing like an old neon light. All for under $15.
