OCD. sometimes things just get to you, like those pesky bags of randomly assorted candies. [Torsten] made a decision to develop a sorting machine capable of sorting Skittles or M&Ms into separate cups by color at around 80 pieces per minute. It’s a fantastic implementation, utilizing an Arduino Duo. He based the code on the principles of a finite-state machine, in buy to make it as quick as possible.
It works as you would expect: When a candy piece is loaded, the color is figured out utilizing an RGB sensor. A 360-degree servo is utilized to move the chute to the appropriate position, as well as interestingly, the system preemptively releases the candy before the chute is in setting in buy to maximize the speed. If you enjoy closely, you can see this habits in the video (embedded after the break).
[Torsten] includes a total expense of materials, if you’d like to try it for yourself. He likewise included a listing of possible improvements.
