Arduino Skittles Sorter

thingiverse

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. https://www.youtube.com/watch?v=9LJ5PrK7l80&t=2s 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. List of non-plastic parts used: - Color sensor : OSEPP Color Sensor (https://www.amazon.ca/gp/product/B00VDKVODS/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1) - Stepper motor and driver : Kuman Stepper motor 28BYJ-48 ULN2003 5V (https://www.amazon.ca/Kuman-Stepper-arduino-28BYJ-48-Breadboard/dp/B01IP2R0CU/ref=sr_1_3?s=electronics&ie=UTF8&qid=1518648406&sr=1-3&keywords=arduino+stepper+motor) - Servo motor : Regular Arduino servo motors (https://www.amazon.ca/RioRand®-Micro-Servo-Airplane-Genuine/dp/B00M8RGGFG/ref=sr_1_1?s=electronics&ie=UTF8&qid=1518648482&sr=1-1&keywords=arduino+servo). - Bearing : Universal standard size 8x22x7w. - Screws and nut : Various length M3. Design improvement list: - The holes on the Arduino connector part are not properly aligned.
