Knock Knock – Wooden Arduino Knocking Calculator

- by - in Games

Knock Knock is a wooden calculator box that is operated by using knocking the surface over which symbol you wish to use. Designed by Khalil Klouche, it’s a pretty good idea aimed to get children doing simple sums. Not quite sure how useful it is when fractions are involved, or counting knocks beyond 20 though, but a pretty impressive project nonetheless!
