Arduino Magnetic Pet Door: Circuit & Code

This video tutorial explains the creation of a magnetically activated Arduino-controlled automatic pet door. The project aims to prevent a dog from accessing a cat's litter box. The tutorial covers the design and functionality of the door, which uses Reed switches and servo motors to control access based on a magnetic collar tag. The video provides a detailed explanation of the circuit setup, including the use of pull-down resistors and the wiring of components. It also delves into the Arduino code, explaining how it monitors sensors and controls the servos to open or close the door. Debugging tips and potential applications of the project are also discussed.
