DIY Smart Robot Car 🚗 | WiFi Controlled using Arduino Nano 33 IoT

Build your own WiFi-controlled smart robot car using the powerful Arduino Nano 33 IoT.
This project demonstrates how to control DC motors wirelessly through a web interface using your smartphone.

The system uses a dual H-bridge driver (L293D motor driver IC), a custom battery-powered setup, and a simple HTTP-based control system. The Arduino acts as a mini web server, allowing real-time control via your phone browser — no app required.

This project is a great introduction to:

* IoT systems
* Robotics fundamentals
* Embedded systems with WiFi
* Real-time motor control

⸻

⚙️ Features

* 📡 WiFi-based control (no Bluetooth required)
* 🌐 Web interface (works on iPhone & Android)
* ⚡ Battery powered (portable system)
* 🔧 DIY build with simple components
* 🚗 Dual DC motor drive system

⸻

🧩 Components Used

* Arduino Nano 33 IoT
* L293D motor driver IC
* TT DC gear motors
* 4× AA battery pack
* Breadboard + jumper wires
* DIY chassis

⸻

🧠 How It Works

The Arduino hosts a small HTTP web server.
When you press a button on your phone:

1. A request is sent over WiFi
2. Arduino receives the command
3. Motor driver activates motors
4. The car moves accordingly

⸻

🚀 Future Improvements

* Joystick-based smooth control
* Mobile app interface
* Camera integration (FPV)
* Obstacle detection
