The MaKey MaKey is a microcontroller about the size of a credit card. By connecting wires to various input points on the board and selectively connecting them to an electrical ground, a student can send digital signals to the board. These signals are then interpreted by the board and sent to a computer as keyboard commands through a USB cable. It requires no software or drivers of any kind. Like a keyboard, it plugs into the USB port and works. So at its most basic level, the MaKey MaKey becomes a keyboard with only six keys: up, down, right, left, enter, and spacebar.
This may seem like a step backward to some. I mean, most of us already have a keyboard that can do a lot more than that. The potential for MaKey MaKey, however, lies in the fact that students can design a computer input device that is not limited to use by one’s fingers. They can invest all their creative energy inventing new ways for people to interact with computers. More importantly, they can do this in a few minutes, with little or no experience in electronics.
A keystroke is triggered when an electrical circuit is completed, and students can use any conductive material to complete these circuits including foil, food, or Play Doh. When you combine the programming language Scratch with a MaKey MaKey, and an open-ended challenge to a student’s creative abilities, it’s easy to imagine the myriad fun, innovative, and (most importantly) authentic project possibilities.
The introductory video on the MaKey MaKey site demonstrates several innovative creations, such as a digital keyboard made of bananas or an interface to Dance Dance Revolution that substitutes buckets of water for the foot pads. These examples help students conceptualize what is possible and prepare students to tackle any number of creative projects grounded in design thinking.
Armed with a MaKey MaKey, my hypothetical sixth grader can absolutely design a video game controller for her disabled brother. She can experiment with a variety of different designs and materials without the fear that her limited knowledge of electronics might have her simply stabbing in the dark or headed down a dead-end path.
This low barrier to entry coupled with the expandability of additional ports and programming create what seems to be the perfect amount of scaffolding for nearly any student to get started. The metaphorical training wheels can be removed for students who are ready, and all students can engage in truly authentic projects that would have been otherwise completely out of their reach.
