Project Instructions

1. Connect two IR sensors at the front bottom of the robot.

2. Place the robot on a surface with a black line track.

3. Program the Arduino to move forward when both sensors detect white.

4. If the left sensor detects black, turn left; if the right sensor detects black, turn right.

5. Keep adjusting speed until it follows the line smoothly.

Materials Required

1. Arduino UNO

2. IR sensor module (x2)

3. L293D Motor Driver Module

4. DC motors with wheels (x2)

5. Chassis board

6. Battery pack (9V or 12V)

7. Jumper wires

Code & Programming

The code reads values from both IR sensors. If both are white → robot moves forward. If one detects black → motor on that side slows down, turning the robot.
