"A MaKey MaKey is a very simple to use piece of kit which can be used to add a little bit more fun to a class coding project.
The MaKey Makey is a bare bones circuit board that connects to your computer via USB. There are7 terminals for attaching electrical wires to it. These are arranged like an old games controller – with up/down/left/right arrows and also spacebar and left click. A strip along the bottom allows for another wire to connect it to Earth."
