DIY Line Following Robot

Hello GYZ welcome to Arduino Projects and in this tutorial i'll show how to make an Line Following Robot using Arduino and some supporting Modules. Line follower Robot follows either a black line or white line, basically there are two types of line follower robots: one is black line follower which follows black line and second is white line follower which follows white line.

In this Arduino based line follower robot i have used IR sensor which has IR Transmitters and IR receivers also called photo diodes. They are used for sending and receiving light. IR transmits infrared lights. When infrared rays falls on white surface, it’s reflected back and catched by photodiodes which generates some voltage changes. When IR light falls on a black surface, light is absorb by the black surface and no rays are reflected back, thus photo diode does not receive any light or rays.
