El tutorial detalla cómo crear un servidor web utilizando el microcontrolador ESP32 para controlar luces LED a través de una red Wi-Fi. Se requiere un desarrollo del ESP32, LED, una placa de prueba, cables de conexión, una computadora para la programación y un resistor para proteger los LED. El proyecto permite a los usuarios encender y apagar las luces LED a través de una página web servida por el ESP32.
Step-by-Step Guide to Creating an ESP32 LED Web Server
- 1. ESP32 LED WEBSERVER: STEP-BY-STEP TUTORIAL Source:
- 2. WHAT IS AN ESP32 WEB SERVER? Source: An ESP32 Web Server is a device that responds to web requests and serves web pages, similar to a traditional computer-based web server. However, instead of using a computer, the ESP32 microcontroller, equipped with built-in WiFi capabilities, handles these tasks. It can both respond to requests and host small web pages, either programmed directly into its code or stored in its flash storage or an SD card.
- 3. MATERIALS NEEDED FOR ESP32 LED CONTROL WEBSERVER Source: To build this project, you'll need: o ESP32 Development Board: Controls LED lights via the web server. o LED Lights: Any type can be used; we've used 2x 5mm LEDs. o Breadboard: Connects LEDs to the ESP32 microcontroller. o Jumper Wires: Links the breadboard, ESP32, and LED lights. o USB Cable: Connects the ESP32 to your computer for programming. o Computer: Required for programming and uploading code. o Resistor: Prevents LED burnout by limiting current flow.
- 4. ESP32 LED WEBSERVER CIRCUIT Source: To connect LED lights to the ESP32: 1.Attach a 220-ohm resistor to GPIO pin 12. 1. Connect the other end of the resistor to the positive leg of one LED. 2. Link the negative leg of the LED to the ESP32's ground (GND). 2.Repeat the process for GPIO pin 14 and the second LED. For Ethernet webserver usage, include an Ethernet shield for the ESP32 board and make slight adjustments to the code.
- 5. ADDING THE ESP32 BOARD TO THE ARDUINO IDE Source: The Arduino IDE offers a user-friendly platform for programming ESP32 boards, catering to both beginners and advanced users. No additional libraries are required for using the web server, as it's integrated into the ESP32 Arduino core. Connecting to the ESP32 Webserver and testing it 1.Open the same network through a device or use the same device to whose hotspot your ESP32 is connected 2.Open a web browser on your computer or mobile device and enter the IP address of the ESP32 board into the address bar.
- 6. WORKING OF ESP32 LED WEBSERVER Source: The project works by creating a web server on the ESP32 microcontroller that serves a web page to a client device, such as a computer or mobile phone, over Wi-Fi. The web page contains controls that allow you to turn the LED lights on or off.
