This project demonstrates how to design and develop a high-performance WiFi Controlled Robot using the Wemos D1 R2 WiFi-Esp8266 Development Board and the L298N Motor Driver Module.
Experience the future of wireless control by using your smartphone as a transmitter. Our custom Android application allows you to control the robotic car's movements seamlessly via voice commands or touch interface over a local WiFi network.
- Advanced Wireless WiFi Communication
- Real-time Android App Control
- Voice Recognition Integration
- Robust Motor Control Logic
Hardware Components
Premium quality components required for building this project.
- Wemos D1 R2: The heart of the project. ESP8266 based development board with integrated WiFi capabilities and Arduino compatibility.
- L298N Motor Driver: High-power dual-channel motor driver capable of controlling the speed and direction of two DC motors simultaneously.
- BO Gear Motors: Set of 4 high-torque DC geared motors with matching plastic tires for smooth movement and traction.
- Robot Chassis: Sturdy 4-wheel acrylic or metal chassis to house all electronics and mechanical components securely.
Circuit Diagram
Follow the wiring guide precisely to ensure proper communication between the ESP8266 and the L298N driver. Check voltage levels to avoid damaging the board.
