MaKey MaKey is an invention kit for the 21st century. Turn everyday objects into touchpads and combine them with the internet to begin physical computing. This simple Invention Kit is great for beginners and experts. Mix computing with crafting, art, engineering, and everything in between. Let's say you load up a piano. Then, instead of using the computer keyboard buttons to play the piano, you can hook up the MaKey MaKey to something fun, like bananas, and the bananas become your piano keys. Go further by creating and coding projects in Scratch and now you can create objects in the physical world that control your digital creations.
