Over half of the people in the world intentionally have pets as their companions, But these pets are becoming burden to the pet owners. There is a lot of stress for the owner while feeding their pets. Over the years different automatic pet feeders are available in the market, but none of them are still not able to solve lot of problems like overeating, obesity. This project aims in rectifying the problems caused by existing feeders and designing an efficient automatic pet feeders using internet of things. This Automatic pet feeder uses a NODEMCU Micro Controller and consists of an interface with DC servo motor, relays, water pump and other hardware equipment. A software code is dumped into the micro controller to perform operations like rotating motors and switching relays on and off. The whole feeder system is controlled using a mobile phone installed with blynk software. The user sends signals to the micro controller using blynk application through blynk cloud. When the DC servo motor runs, the motor rotates the propeller which is in the feeding device, which drops down pet food through the pipe into perforated feeding bowl. The water pump will be kept in a tank containing water. When the water pump runs, the water is pumped into the water bowl of pet. So, the pet will receive regular amounts of food and water on a steady feeding schedule.
