“Arduino Line Follower Robot
In this tutorial, we will discuss the working of an Arduino line following robot which will follow a black line in white background and take the correct turn whenever it reaches curves in its path.
Arduino Line Follower Components
IR Sensor (Array Sensor or 2 Individual Sensors)
You all might be familiar with Arduino; which is the most widely used and fastly evolving electronic platform with so many microcontroller boards and software. For our line following robot, I will be using Arduino UNO which is the most commonly used board.
The Arduino Nano is the best option to get started with electronics and coding if this is your first experience with Arduino Platform. You can use any Arduino Board for this project.
As mentioned earlier, our line following robot will be following a black line in a white background. So we need something that will ‘see’ the line and tell the line follower to follow the line or to turn around if it is going away from the line. For this purpose, we will be using an IR (Infra Red) Sensor.”
