The dispenser is the part of the project that will extract one candy at a time from the bin. It's not as easy as it sounds. My design is inspired by other builds found on the web, but I increased the number of holes in the rotating plate to have a higher throughput. There is no good reason to use a stepper motor, other than the fact that I had this motor lying around for years. It's also an opportunity for me to play with a 555 chip to generate the pulse train (schematic).
