Introduction to Line Path Follower:- Line follower is a machine that can

follow a path. The path can be visible like a black line on a white surface (or vice-versa).

In my project the robot will be able to detect white line only leaving all other colors undetected.

Components used :-

LDR, LED’s & LM324 (Op-amp) IC to design sensors.

74LS04, 74LS08 to interface sensors with motors using L293D (Motor driving ) IC.

7805 voltage regulator IC for Regulated power supply.

DC gear motors( 100 rpm).

Conclusion :-

The line path follower system that I have its practical use in various companies like in construction companies.

It’s limitation is that it is affected by environmental condition.
