"arduino is a tool for making computers that can sense and control more of the physical world than your desktop computer. it's an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board."--arduino.cc website.

"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. each bit has a specific function (light, sound, sensors, buttons, thresholds, pulse, motors, etc), and modules snap to make larger circuits. ... littlebits are small, simple, intuitive, blocks that make creating with sophisticated electronics a matter of snapping small magnets together."--littlebits website.

makey makey is an invention kit for the 21st century. turn everyday objects into touchpads and combine them with the internet. it's a simple invention kit for beginners and experts doing art, engineering, and everything in between.
