How do you make a simple line follower robot with Arduino?

How do you make a simple line follower robot with Arduino?


  1. Step 1: Connect the circuit as shown in the schematic.
  2. Step 2: Use the Arduino IDE to write your own code.
  3. Step 3: Upload your code to the Arduino and connect it to the batteries or you can even use a power bank to run the Arduino.
  4. Step 4: Test it on a black path.

What is line follower robot Arduino?

As the name suggests, the line follower robot is an automated vehicle that follows a visual line embedded on the surface. This visual line is a path on which the line follower robot runs. Generally, it uses a black line on a white surface, or you can adjust it as a white line on a black surface.

How does a line following robot works?

A line follower consists of an infrared light sensor and an infrared LED. It works by illuminating a surface with infrared light; the sensor then picks up the reflected infrared radiation and, based on its intensity, determines the reflectivity of the surface in question.

What is simple line follower?

May 14, 2012. It is a machine that follows a line, either a black line on white surface or vise-versa. For Beginners it is usually their first robot to play with. In this tutorial, we will teach you to make the line follower robot move on the line with a type of feedback mechanism.

What is the line follower sensor?

The Line Follower sensor is an add-on for your RedBot that gives your robot the ability to detect lines or nearby objects. The sensor works by detecting reflected light coming from its own infrared LED.

Is a line follower analog or digital?

The Line Tracker is an analog sensor, meaning that it can output many more values within its range of potential values (in this case, from 0-5V) than a digital sensor, which would output only a handful of discrete values in the range (e.g., 1, 2, 3, 4, and 5V), as is the case for a digital sensor.

What is the uses of line following robot?

The sensor based black line follower robots are one of the most basic robots used to follow black line on white background or vice versa. These robots may be used to in various industrial and domestic applications such as to carry goods, floor cleaning, delivery services and transportation.

How do line following robots work?

How does the Arduino know where the line is on the robot?

Every one of the 5 sensors are detecting the brightness under them and depending on these readings, the Arduino can know where the line is in relation to the middle of the robot, where it should be.

How to program a robot with an Arduino?

The USB port in the Arduino should be facing to the back of the robot since we will be connecting to it when we program the robot. Now that we have the base completed, we need to attach the sensor holder which holds the sensor board and a ball caster that provides a low friction support to the robot.

What is Arduino line follower Robot?

Here in this arduino line follower robot when sensor senses white surface then arduino gets 1 as input and when senses black line arduino gets 0 as input. The whole arduino line follower robot can be divided into 3 sections: sensor section, control section and driver section.

How do I get my Robot to follow a line?

Unplug your robot from the USB and set your robot on your lined course and turn it on. You should see the robot turn back and forth over the line and begin following. You can “tune” some of the variables in the sketch to affect its performance.
