This is an M&M dispenser that was made for a research study to test human motivation and attention for food rewards. It uses the Adafruit Feather M4 express for control, and a ULN2003 Feather board to control the dispensing motor. Also includes a beam-bream to detect when the M&M is dropped, as well as a TRRS jack to enable computer control via the GPIOs.”
