It is no secret that cats love to hunt. But indoor cats don’t get that opportunity. This smart cat feeder by Ben Millam aims to change that. The idea here is simple.

The developer used a Super Feed pet feeder, Arduino Uno, Adafruit Arduino RFID Shield, and a few other parts to pull this off. He used an RFID reader to detect RFID tags embedded in the balls. More information is available here.
