Sort your M&Ms or Skittles with this ingenious machine
Inspired by a YouTube video of another candy sorter, Willem Pennings decided to build his own version.
After nearly eight months of work, he now has a device that can separate M&Ms or Skittles into their respective color dishes. Control is accomplished via a pair of Arduino Nano boards along with two EasyDrivers and an RGB sensor. These actuate a small servo for mixing the candies, and a stepper motor to properly position the candy tube.
Besides designing the controls for the machine, everything is modeled beautifully in the NX10 CAD package. The results, as seen in the video, look extremely polished–and it’s quite soothing to watch these candies drop into their little bowls in automated fashion!
