In the Makey Makey unit we learned how simple circuits work and how to make really anything into a switch or button. I would change how we built our skee-golf because it barley worked.
I only have footage of one of the challenges prior to the project, and it was the game button. I learned how to create simple circuits, and that Makey Makey is a fun easy toy. I would change how messy my wires were.
