3D-printed machine sorts Skittles by colour An Arduino-powered DIY project uses a colour sensor to automatically sort and separate Skittles.

Automated color-detection object sorting has revolutionized several industries, including manufacturing, logistics, and recycling. The systems that use Arduino UNO microcontrollers for color sorting ...

The machine itself is beautifully-made with a handsome painted wooden case and 3D printed internal machinery. The sorter uses two Arduino Nanos and two EasyDrivers to control the sensor and the ...
