Hi I’ve got 3 cats who each have their own special dried food and and shouldn’t eat each other’s food.
I had an idea of a box divided inside with the 3 different bowls of food and a servo controlling a lid for each cat.
Does anyone know of a sensor that could detect which cat is at the box and which lid to lift up accordingly possibly by having an identification “chip” hanging from their collar? They all have identification chips inside their bodies but I’d imagine it would be quite tricky and expensive to implement reading them.
Thanks for any imput or alternative ideas
I think you can do that with NFC tag,you can attach it to your cat collar.
