CODES

The document outlines a DIY project for an IoT-based door locker using an ESP8266 microcontroller. It includes Arduino code for setting up a web server that allows users to lock/unlock the door and enable/disable a sensor. The code manages the door locking mechanism based on distance measurements from the sensor.
