Picture of Learn How to Count Money With Coins Using the MaKey MaKey!

Learn how to recognize and count with coins using the MaKey MaKey. Anyone with a MaKey MaKey can create this educational tool for kids. The software is written in Scratch, which can be modified in order to go deeper in using coins as well as Scratch programming. We hope that you have fun!

Required materials:

  • 1 x MaKey MaKey
  • 1 x USB Cable
  • 1 x PC
  • 1 x Quarter
  • 1 x Dime
  • 1 x Nickel
  • 1 x Penny

Step 1: Connect the Ground Signal

Cool! It might help to clarify the purpose in your intro a bit more. I thought I might learn to make a coin-counting, Coinstar-like device. Instead, this is a tool to identify coins by denomination. (Or perhaps I am dense. Always a possibility.)

Regardless, this is a great use of Makey Makey and Scratch.

Hi wilgubeast, great point! I updated the intro to try to clarify a bit more. I hope that it helps. Thanks for the positive feedback ;).

I feel fourteen percent less dense. :D Thanks for clarifying. (When version 2.0 identifies the coins by their resistance or surface capacitance or whatever, I'd like to put in a feature request for identifying coins in my pockets without removing them from my pockets. I got $5 on the kickstarter...)

No problem! Great idea. Could be a fun project! :)
