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. Simply combine the different littleBits together and start creating your own design made of sensors, motors, input and output modules.
