In this instructable I will explain how to make a simple RFID pet food access control system. This system uses a stand-alone RFID system that can be purchased either pre-assembled or in kit form if you desire to do the soldering yourself, and also wish to save a few dollars in the process.

The reason I made this was out of pure necessity. I have two dogs, and when my vet placed one of them on a special diet I needed some way to ensure they ate their own food… and only their own food. Since they are open-bowl fed and I’m gone part of the day, I decided to look for a product that would do what I needed. This meant I wouldn’t have to spend a great deal of time trying to re-train them and still give them the freedom to eat whenever they chose. This is where my frustrations begun…

  1. what would be a really cool adaptation of this project would be using the rfid chips that many pets have implanted in case they are lost.

  2. The RFID tags used here are probably not the same as the vet uses. You can buy RFID tags online with a reader. It may not read the pet info, but you would write your own info to the tags. Like Dog1 and Dog2.

    Instead of the sound, you could use a linear actuator to cover the bowl if the unauthorized dog tried to eat it.
