🌐 Control Your LED from a Web Server Using ESP32 Introduction

This tutorial is designed for makers who have already learned how to blink an LED, connect an external one, and control it using a button. The goal of this tutorial is to control the LED using a simple web interface hosted directly on the ESP32 development board. By the end of the tutorial, users will be able to open a webpage on their phone or computer and turn the LED on or off wirelessly. To complete the project, users will need an ESP32 development board, an LED, a resistor, a breadboard, jumper wires, and a Wi-Fi network. The first step is to set up the breadboard and circuit, which involves connecting the LED to the ESP32 and adding a resistor to limit the current. The next step is to write the code, which involves opening the Arduino IDE and pasting in the provided code, replacing the Wi-Fi credentials with the user's own network information. The code sets up a Wi-Fi server and listens for incoming connections, allowing users to control the LED by sending requests to the ESP32's IP address. Once the code is uploaded and the ESP32 is connected to the Wi-Fi network, users can open a browser and navigate to the ESP32's IP address to access the control page. The control page features two buttons that allow users to turn the LED on or off, and the LED should respond instantly to these commands. If users encounter any issues, they can refer to the troubleshooting section for help.
