Arduino Skittles Sorter by MxBoud

Last crawled date: 3 years ago

I spend the 2017 Christmas holidays building this Arduino controlled Skittles colors sorter.
The machine is not working perfectly yet (see video). It has a color sorting success rate of about 95 % and has some feeder jamming problems.

Still... I think this is a pretty cool device and it made me learn a lot of stuff about design and C++ Arduino coding. It took about 40 hours to print all the parts on my Prusa I3 clone.
The Arduino script is available on GitHub: https://github.com/MxBoud/Arduino-Skittles-Sorter.
