Skittles Sorting Machine

Skittles Sorting Machine

Do you like your rainbow of flavor to be sorted by discrete wavelength? If so, then you’ll appreciate Brian Egenriether’s Skittles Sorting Machine 2. Using an IR LED and phototransistor to determine the appropriate color, a BASIC Stamp 2 controls three servo motors to actuate a turnstile and chute selector to deliver the identified confection to a predetermined collection bowl.
