We have even more cool projects for you to learn how to build here: https://www.electromaker.io/kits This Arduino-powered machine separates coins of different dominations and then tallies up their total value. This is shown on an 8 digit 7 segment display. Reflected infrared sensors (TCRT5000s) are used to detect the coins.
