This is a video of our cat with special dietary needs using her RFID feeder. It is made from an hacked cd-rom drive and an Arduino with a RFID reader attached. It also uses a PIR (Passive InfraRed) sensor to make sure it doesn’t close on the cat. It has actually saved us considerable money as the food is very expensive and the other cats love to eat it, so both a fun and very useful project!
