Project Introduction
Wi-Fi LED Controller is a simple IoT project that uses an ESP32, LED, and resistor to control an LED wirelessly. The ESP32 connects to a Wi-Fi network and receives commands from a smartphone or computer through a simple web interface. When the user selects ON or OFF, the ESP32 changes the LED state through one of its GPIO pins.
This project is a good beginner exercise for learning ESP32 programming, Wi-Fi communication, GPIO control, and basic web-server operation. The LED is connected to an ESP32 GPIO pin through a current-limiting resistor, while the ESP32 handles the wireless commands. The project can later be expanded to control multiple LEDs, adjust LED brightness, or operate other low-voltage devices.
