The LED Project Handbook is a collection of 11 interactive, exciting projects from a group of the world's most famous makers. Following a quick primer on how LEDs work, readers learn to combine LEDs with the Arduino and Raspberry Pi to build quirky projects like a sea-urchin lamp, an illuminated UFO desktop model, a cheater's dice-roller for boardgames, an LED music visualiser, and a 'magic' wand that uses gesture recognition to turn lights on and off.
