Automatic Pet Feeding System Using Google Assistant and Node MCU

Pet owners these days want to enjoy the company with their pets, some pet owners have the time to feed their pets and some do not have the time to do so. To overcome this situation automation and (IoT) comes into existence to develop a system that can fulfil the pet owner requirement without doing any harm to their pets. Google assistant controlled automated pet feeder machine is simple, efficient and also cost effective. Using this machine pet owners can feed their pet by Google Assistant which is inbuilt on most of the Android Smartphone from anywhere around the world. Still, people who have a fairly busy schedule in terms of work will have difficulty maintaining ornamental pets, especially when leaving the house in a short time. The purpose of this study is to design a tool that can help the community in terms of scheduling feeding times and automatic water changes in the aquarium and being able to monitor the condition of the aquarium in real-time via an Android smartphone by utilizing the Internet of Things (IoT) technology. This Automatic pet feeder uses a NODEMCU and Arduino 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 Adafruit software. The user sends signals to the micro controller using Google application through Adafruit cloud. When the DC servo motor runs.
