ESP32 Asynchronous Web Server (with IP Display on LCD)

In this project, we’re turning the ESP32 into an **asynchronous web server** that you can control from your phone or computer on the same Wi-Fi network. Thanks to the ESPAsyncWebServer library, the server can process multiple requests simultaneously (unlike the classic `WebServer.h`, which blocks on a single request). You’ll be able to open the ESP32’s IP address in a browser and click the ON/OFF buttons (the `/on` and `/off` routes) to turn the LED connected to GPIO 5 on and off.
