I love the creativity of expanding the ideas learnt in a Scratch lesson into something physical. Makey Makey is a microcontroller that allows the user to utilize limited range of keys on a keyboard to control what happens on a computer device such as a Chromebook. Therefore, it is a great way to develop a digital outcome. This example project allows students to learn the basics of coding and using a Makey Makey through making a 'Cardboard Piano'.
To create a cardboard piano using the following:
The Makey Makey takes the place of several keys on a keyboard. It works by conducting electricity through a circuit and this represents the pressing of the Up, Down, Left, Right and Space keys as well as the letters W, A, S, D, F and G.
The code is assigned to each note by using blocks in Scratch.
The code is then put together for each note
To play the piano, a cardboard keyboard is made and attached using crocodile clips.
Other examples of the use of a Makey Makey could be to create a controller for the Scratch Maze Game
