esp32-web-server: LED Control

A beginner-friendly Internet of Things (IoT) project that turns an ESP32 microcontroller into a standalone Wi-Fi web server. By connecting to this server through any web browser on your local network, you can wirelessly control the ESP32's built-in LED.

Hardware Requirements

• Any standard ESP32 Development Board
• A data-capable Micro-USB or USB-C cable (ensure it is not a "charge-only" cable)
• A computer (Windows, Mac, or Linux)
• A local Wi-Fi network

Software Setup

1. Install the Arduino IDE: Download and install it from the official Arduino website.
2. Install the ESP32 Board Add-on:
   • Open the Arduino IDE. Go to File > Preferences.
   • In the "Additional Boards Manager URLs" field, paste: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
   • Go to Tools > Board > Boards Manager, search for "esp32", and install the package by Espressif Systems.
3. USB Drivers: If your computer does not recognize the ESP32 port, you may need to install the USB-to-Serial drivers (usually CP210x or CH340 depending on your specific board model).

Step-by-Step Usage Guide

1. Configure the Code

1. Clone this repository or download the files.
2. Open the ESP32_Web_Server/ESP32_Web_Server.ino file in the Arduino IDE.
3. Update the network credentials in the code to match your home network:

   const char* ssid = "YOUR_WIFI_NETWORK_NAME";
   const char* password = "YOUR_WIFI_PASSWORD";

2. Upload to the ESP32

1. Plug your ESP32 into your computer.
2. In the Arduino IDE, go to Tools > Board and select your specific ESP32 model (e.g., "DOIT ESP32 DEVKIT V1").
3. Go to Tools > Port and select the COM port for your ESP32.
4. Click the Upload button (the right-pointing arrow at the top left).

3. Connect and Test

1. Once the upload reads "Done uploading", open the Serial Monitor (the magnifying glass icon in the top right).
2. Set the baud rate in the bottom right corner of the Serial Monitor to 115200.
3. Press the physical EN or RST button on your ESP32 board to restart it.
4. Watch the Serial Monitor. Once it connects to your Wi-Fi, it will print a local IP address (e.g., 192.168.1.45).
5. Open any web browser on a phone or computer connected to the same Wi-Fi network.
6. Type the IP address into the browser's address bar and hit enter.
7. You should see a webpage with "Turn ON" and "Turn OFF" buttons. Click them to control the physical LED on your board!
