🔍 Project Overview

This project uses an ESP32-CAM module to build a Wi-Fi controlled robot car with live video streaming and real-time motor control. The robot can be operated from a mobile browser over Wi-Fi while transmitting live camera feed.

The system runs independently using the ESP32’s built-in Wi-Fi — no external microcontroller required. It is suitable for surveillance, robotics learning, and IoT-based automation projects.

⚙️ How It Works (Short & Simple)

Camera streams live video
The ESP32-CAM captures and streams video over Wi-Fi through a web server hosted on the board.

Mobile connects via Wi-Fi
User connects to the ESP32’s IP address using a smartphone browser.

Motor driver controls movement
A motor driver module (like L298N or L293D) receives GPIO signals from ESP32 to control direction:

• Forward
• Backward
• Left
• Right
• Stop

Real-time monitoring
User sees live camera feed while controlling the robot.

Standalone system
No cloud dependency — works on local Wi-Fi network.
