DIY Nespresso Capsule Detector

If there’s one thing that we geeks love, it’s coffee. We always buy a lot of different capsules for our workshop, put them in a jar, and then we have no idea which color to pick. So we came up with the Nespresso capsule detector. The idea is pretty simple: Drop a capsule into the tube, and once it’s completely dark, a single LED lights up. The RGB light sensor reads the brightness level of each color channel - Red, Green and Blue. It then sends the values to the Arduino, which recognizes the capsule based on the pre-defined values in the code. This project will include code, electronic diagram and STL files. It’ll also include instructions on how to use, an electronic scheme and code web-app we’re developing. You are welcome to try it.”
