We would like to introduce a nice project makes with different components, put together to sort M&Ms and Skittles!

It makes with Arduino controller, stepper motors, an RGB color sensor and 3D-printed parts to sort several types of candy by their respect colors.

The machine is able to sort M&M’s and Skittles by colour by performing optical measurements using the RGB sensor. It can be modified to sort any type of coloured object, as long as the individual pieces have a regular shape with even dimensions. It takes approximately 2-3 minutes to sort a 300 g bag of Skittles / M&M’s and sorts about 2 pieces per second. The machine is 250 mm in diameter and approximately 300 mm in height.
