IoT(Internet of things) Raspberry pi Pet feeder : In this video, I have created the basic flow wherein I have developed a very simple iOS app that communicates with the Spring Boot service deployed on Raspberry pi, which in turn executes the python script that controls the servo motor. In a later video, I will create a pet feeder box and fit this Raspberry pi servo motor inside, and then using the iOS app that we built in this tutorial we can control opening/closing of the feeder door to dispense food. Also, i will be adding many more functionalities to this pet feeder.
