LEDs are perfect for creating brilliant, energy efficient lighting displays. With LEDs, the possibilities are endless! You can use a microcontroller to animate and change colors, or even wire them up on your car or computer case to create just the right look. 10mm LEDs in particular create BIG displays, and you only need a few to light up a room. These LEDs also work great with your Arduino, Raspberry Pi or BoardX project since they can be driven directly from the control pins of these boards, no boost or drive circuitry required!
