Year 4 enjoyed the wonders of Makey Makey recently, working together to programme a keyboard using carrots! Their computing unit, We Are Musicians, has been exciting and unusual enough up until now, but their final lesson was something else…
Firstly, we connected the Makey Makey board to a simple keyboard programme on the laptop. Then we programmed Makey Makey to replace the keys on the keyboard with a different input – carrots! By touching the carrots, the children completed the circuit, allowing the current to flow through the wire, the carrots and their own body. This then triggered the output – the sound!
We even went on the replace the carrots with different input devices. Instead of carrots, we used people! We are just as conductive as carrots (as we contain a lot of water) so we could be used as part of the circuit too. So by touching another person who is connected to the wires in the circuit, as seen in the pictures below, you could play sounds.
What other objects do you think we could use as inputs?
We even managed to play some really nice melodies by using a group of children and setting each child up to be the input for a certain note. Then by attaching themselves to the circuit, another child becomes the keyboard player. They can then connect to each child to play a different sound.
We’ll see much more of Makey Makey soon in other computing units. Until then, Makey Makey is normally set up in the Infant ICT suite for a variety of fun activities. Come and take a look!
