MaKey MaKey: An Invention Kit for Everyone
Alligator Clip two objects to the MaKey MaKey board. For example, you and an apple. When you touch the apple, you make a connection, and MaKey MaKey sends the computer a keyboard message. The computer just thinks MaKey MaKey is a regular keyboard (or mouse). Therefore it works with all programs and webpages, because all programs and webpages take keyboard and mouse input.
The back of the board has hookups for 6 keyboard keys, and mouse control. It also has the open hardware logo, a link for help getting started, and an area for using the board in Arduino mode.
