Project Details
How It Works
How It WorksThe ESP32 connects to a Wi-Fi network and prepares HTTP requests (GET or POST). For GET requests, data is sent via URL parameters. For POST requests, data is sent in the request body (e.g., as JSON). The server processes the request and returns a response, which the ESP32 receives and parses. This enables bidirectional communication between the IoT device and web services.
Prerequisites
Basic knowledge of C++ programming, familiarity with Arduino IDE, and understanding of HTTP protocol basics. Access to a Wi-Fi network and a computer for development.
