How to Make Line Following Robotic Car Without Arduino | Plug & Play IR Sensor + Relay Module | MR Tech Box

🚗 Learn How to Make a Line Following Robotic Car Without Arduino or Coding!
In this video, I’ll show you step-by-step how to build a plug & play Line Follower Robot using just IR sensors and relay modules — no microcontroller required!
This is one of the simplest and smartest science/engineering projects you can make at home or for your school/college exhibition.
🧩 Working Principle:
Each IR sensor detects the black/white line and sends a signal to the relay module, which controls the direction of the motors automatically — allowing the robot car to follow the path smoothly.
💡 Why You’ll Love This Project:
✅ No Arduino or coding required
✅ Fully automatic line detection
✅ Simple Plug & Play concept
✅ Best for school & college science exhibitions
