Line Follower Robot Car

This Arduino-powered line follower robot is designed to:

• Detect and follow a black line on a white surface using an array of 6 infrared (IR) sensors.

• Adjust its direction dynamically to the left or right based on sensor input to stay on track.

• Stop safely when the line is lost or not detected by any of the sensors.

How It Works

The robot continuously reads input from 6 IR sensors arranged from left to right. Based on which sensors detect the black line:

• If the middle sensors detect the line → it moves forward.

• If the left-side sensors detect the line → it turns left.

• If the right-side sensors detect the line → it turns right.

• If no sensors detect the line → it stops to prevent going off-track.
