Color Sorting Machine | Arduino Controlled

Can someone please help? Which servo is being used to turn the main plate?

The layout.pdf does not have any assembly instructions. Is the video what is available for build info?

Are there instructions on a pdf or just the Youtube video?

Thanks, Carlos. The kids love it. This is version 1 for me. I don't have the color sensor yet. So for now i programmed it for manually sorting the skittles.
