Arduino Skittles Sorter

thingiverse

I spend a significant amount of time during the 2017 Christmas holidays building this Arduino controlled Skittles colors sorter. The machine is not functioning flawlessly yet, as seen in the video provided. It has achieved a color sorting success rate of approximately 95 percent and has encountered issues with feeder jamming. https://www.youtube.com/watch?v=9LJ5PrK7l80&t=2s Despite its current limitations, I believe this device is quite impressive, and it has taught me a great deal about design and C++ Arduino coding. It took around 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. Here's a list of non-plastic components 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%EF%BC%88Micro-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.
