Line Follower Robot Car with Arduino

Line Follower Robot Car with Arduino – Easy DIY Project Guide

Introduction

Looking for a simple yet exciting Arduino project? Building a Line Follower Robot Car using Arduino is one of the best DIY projects for beginners, school students, and hobbyists. This project teaches robotics fundamentals, sensor integration, and Arduino coding in a fun way. At Stemvolt, we provide all required components and kits to make your Line Follower project successful.

What is a Line Follower Robot?

A Line Follower Robot is an autonomous robot that follows a specific path, usually a black line on a white surface, using infrared (IR) sensors. This robot detects the line using sensors and moves accordingly by controlling the motors via an Arduino microcontroller.

Components Required to Build Line Follower Robot Car

To build a basic line follower car, you will need:

• Arduino UNO Board
• L298N Motor Driver Module
• IR Sensor Module (Pair)
• DC Motors (2 units) with Wheels
• Chassis (robot frame)
• Caster Wheel
• Power Supply (Battery 9V/12V)
• Jumper Wires and Basic Tools

You can buy a complete Line Follower DIY Kit from Stemvolt.in with fast shipping and expert support.

How Does a Line Follower Robot Work?

• IR Sensors detect the black line and send signals to Arduino.
• Arduino processes the input and sends output signals to the motor driver.
• Based on the sensor readings, the motors rotate to keep the robot following the line.
• When the robot detects a turn or curve, it adjusts motor speed to follow the path.

Basic Working Logic (Arduino Code Concept):

• IF left sensor detects black and right detects white → turn left
• IF right sensor detects black and left detects white → turn right
• IF both sensors detect black → go forward
• IF both sensors detect white → stop or take action
