littleBits makes an open source library of electronic modules that snap together with tiny magnets for prototyping, learning, and fun. littleBits consists of tiny circuit-boards with specific functions engineered to snap together with magnets. No soldering, no wiring, no programming, just snap together for prototyping, learning and fun. Crave creativity? Make something! Light it, push it, turn it, twist it, bend it, buzz it, blink it, shake it (light, sound, sensors, buttons, thresholds, pulse, motors, etc), and modules snap to make larger circuits.
