Building a WiFi-Controlled Car with ESP32
A WiFi-controlled car built using ESP32, L298N motor driver, and WebSocket communication for real-time control.
Project Overview
This project involves creating a WiFi-controlled car using an ESP32 microcontroller, L298N motor driver, 4-wheel car chassis, and a Li-ion battery. The car can be controlled wirelessly via a web interface using WebSockets.
The assembly process included connecting motors to the L298N motor driver, interfacing it with ESP32, and powering the system with a Li-ion battery. The ESP32 was programmed using Arduino IDE with WebSockets integration for smooth real-time control.
Key learnings include ESP32 programming, L298N motor driver usage, Arduino basics, and WebSocket communication. The project also involved solving challenges like WebSocket integration, chassis assembly, and control page design.
The final outcome is a car that can be smoothly controlled in real-time with an intuitive web-based interface, making it an exciting IoT and embedded systems project.
