The machine runs on an Arduino Uno board, and uses a TCS3200 programmable colour sensor to detect the colours of the Skittles.

After seeing a color-sorting machine years back, Pennings decided to create his own and use it for the ultimate good: to sort shitty Skittles flavors so we don’t have to eat them.

The machine is 250 mm in diameter and approximately 300 mm in height,” writes Pennings. The system uses an RGB sensor to assess the color of the candy and place it into the proper dish.
