ESP32 Network Monitor

This project sets up an ESP32 as a Wi-Fi access point and monitors connected devices. It provides a web-based dashboard to display connected devices' MAC addresses and IPs in a network map visualization.

Features

• ESP32 Access Point: Creates a local Wi-Fi network.
• Device Monitoring: Tracks connected devices (MAC & IP).
• Web Dashboard: Displays connected devices in an interactive UI.
• Live Updates: Fetches device details dynamically every 2 seconds.

Hardware Requirements

• ESP32 Development Board
• USB Cable for Power & Programming
• Computer with Arduino IDE or PlatformIO

Software Requirements

• Arduino IDE (or PlatformIO)
• ESP32 Board Support Package
• WiFi.h, WebServer.h, esp_wifi.h, esp_netif.h

1. Clone the Repository

   git clone https://github.com/yourusername/ESP32-Network-Monitor.git
   cd ESP32-Network-Monitor

2. Open the Project in Arduino IDE
3. Install ESP32 Board Support (if not already installed):
   • Go to File > Preferences
   • Add https://dl.espressif.com/dl/package_esp32_index.json under Additional Board Manager URLs
   • Open Board Manager and install ESP32 by Espressif Systems
4. Connect Your ESP32 Board & Select the Correct Port
