Skittles candies come in various vibrant colors. While they may be a tasty treat, JohnO3 had another idea: to create an amazing automated display for the little circles.
On top of the shuttle mechanism, eight boxes release the correct flavor/color into an intermediate tube via individual metal gear servos. The Arduino then commands the linear axis to move the funnel to the appropriate bin. This process is repeated 2,760 times until an image, measuring up to 785 x 610mm (31 x 24 inches), is completed.
The Skittle Pixel8r an incredible build, and perhaps we could see it expanded even further to not just dispense, but also sort Skittles as an all-in-one auto art installation! Code and files for the project can be found here.
