“My name is Calvin and I will show you how to make an Infrared dice sensor and explain how it works.
I am currently a Taylor University student studying Computer Engineering and my team and I was asked to design and build a mechanism that can sort any object that can fit in a 1in square. We could have taken the easy route and chosen to sort m&m’s using a simple color sensor, but we decided to go above and beyond and sort dice by the number shown. After countless hours of trying to find a guide on how to read the face of the dice I ran into this link here:
https://makezine.com/2009/09/19/dice-reader-versio…
This link, however, did not give me much more than the idea on how to read the face of the dice, so using the idea that was provided, I went on my way to build and develop a sensor that can be connected with an Arduino with ease and can read the face of the dice as accurately as possible, thus giving us this Infrared Dice Sensor.
