The MaKey MaKey uses a USB cord to connect its circuit board to your computer. The circuit board takes over the functionality of certain key on your keyboard or mouse, like the space bar or the mouse click. That is where the fun begins. Using alligator clips you can connect the space bar function of the MaKey MaKey controller to the end of a banana, or a pencil, or a piece of Play-Doh, and make that object the keyboard or mouse input. Just touch your “banana” and you control the functionality of the space bar on the computer. Go out and find some cool applications and let your creativity run wild!
