Make a Line Follower Robot using Arduino

Robotics is fascinating! If you are well aware of basics of Arduino, you can build a simple line follower robot with a little coding and only few connections.

Line Follower Robot using Arduino

The concept of this arduino based line follower robot is quite easy and related to light. We have used here the behaviour of light at black and white surface. When light fall on a white surface it is almost full reflected and in case of black surface light is completely absorbed. This behaviour of light is used in building a line follower robot.

An IR transmitter and receiver module is used to identify the black line, along with Arduino and DC motors and motor driver IC.

Here you can watch the video showing the line follower robot in action
