ESP32 REST API Client Embedded App

Overview

This project is a sample embedded application for the ESP32 microcontroller, showcasing WiFi connectivity and REST API client interactions. It demonstrates JSON serialization/deserialization, HTTP POST and GET requests, and basic IoT functionality using the Arduino framework. The project is designed to run on the ESP32 DevKit-C V4 board and is simulated on the Wokwi platform.

Features

• Connects to a WiFi network using predefined credentials.
• Sends a POST request with a JSON payload to a REST API endpoint.
• Retrieves data via a GET request and processes the JSON response.
• Displays connection details and API responses via the serial monitor.
• Simulated on Wokwi for easy testing and development.

Prerequisites

To run this project, you need:

• An ESP32 DevKit-C V4 board (for hardware deployment) or access to Wokwi for simulation.
• Arduino IDE or a compatible development environment.
• The following Arduino libraries:
  • ArduinoJson
  • WiFi
  • HTTPClient
• A stable internet connection for WiFi and API communication.
