“Want to be able to feed your dog in a timely manner every day but always lose track of time? Look no further; this Instructable will teach you how to build your own Arduino-powered dog food dispenser. I made this for my Students Involved in Discovering Engineering (SIDE) Project for Ms. Berbawy’s Principles of Engineering class. The project was a great experience to learn basic circuitry and coding and improve my CAD and Adobe Illustrator skills.
Note: This project’s inspiration was an Instructable for an Arduino Controlled Dog Food/Treat Dispenser by crazydeadmoth. Multiple changes were incorporated in the design to facilitate easy maintenance, increase stored food capacity, and select the amount of food to be dispensed.
