Description

This food pellet dispenser was developed by Dr. Andrew Maurer's Lab in the McKnight Brain Institute at the University of Florida. The dispenser consists of four separate 3D printed components and uses a bipolar stepper motor to dispense individual 45mg food pellets. An infrared break-beam attached to one of the external interrupt pins is used to keep track of how many pellets have been dispensed. The dispenser is designed to be operated with an Arduino using an Adafruit motor driver shield and a size nema 14 stepper motor. See the supplemental documentation for more details and part lists.
