littleBits (spelled lower case L, upper case B, all one word) 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. Each bit has a specific function (light, sound, sensors, buttons, thresholds, pulse, motors, etc), and modules snap to make larger circuits. Just as LEGO™ allows you to create complex structures with very little engineering knowledge, littleBits are small, simple, intuitive, blocks that make creating with sophisticated electronics a matter of snapping small magnets together.
