Wi-Fi Controlled Hybrid Car

Wi-Fi Controlled Hybrid Car

Project Overview

The Wi-Fi Controlled Hybrid Car is a smart vehicle system that combines hybrid energy sources with wireless control using Wi-Fi technology. The car can be controlled remotely through a mobile application or web interface, allowing users to operate movement and monitor system status in real time.

This project demonstrates the integration of renewable energy, embedded systems, and IoT-based vehicle control, making it ideal for modern smart transportation concepts.

Working Principle

The system works by combining multiple power sources and Wi-Fi communication for vehicle control.

1. The hybrid car uses two power sources (such as battery + solar panel).

2. A Wi-Fi-enabled microcontroller (ESP8266 / ESP32) acts as the main control unit.

3. Commands are sent from a smartphone or web dashboard over Wi-Fi.

4. The microcontroller receives commands and controls:

   • Motor direction (forward, backward)

   • Speed control

   • Turning (left/right)

5. Power management circuitry switches or balances energy between sources.

6. The vehicle moves according to the received commands in real time.
