Turning a Basic Arduino 2WD Robot Into a Line Follower With 2 x FC 51 Infrared Sensors

Turning a Basic Arduino 2WD Robot Into a Line Follower With 2 x FC 51 Infrared Sensors

In this video, I'm upgrading the basic Arduino 2WD robot from the previous videos into an intelligent line follower using 2 x FC 51 infrared sensors!

00:00 Introduction
00:30 Required components
00:45 Wiring updates
03:09 Connecting the IR sensors
04:50 Testing and calibrating the IR sensors
05:58 Optional 3d printed IR sensor mount
07:38 Arduino setup and code
08:47 Initial line following test
09:09 Updating the battery
09:36 End result

A step-by-step guide through the entire process, from wiring the sensors to the Arduino and breadboard to the code that enables the robot to detect and follow a line. It also highlights some of the issues I had and improvements I made. This project is perfect for those looking to add some slightly more advanced functionality to their robot builds, making it capable of navigating tracks on its own.

What You’ll Learn:
* How to wire the FC 51 infrared sensors to the Arduino and breadboard.
* Programming the Arduino to process sensor input and control the robot’s movement.
* Practical tips for optimising sensor placement and calibration.

Using FC 51 Infrared Sensors:
Reliable and affordable sensors for detecting black-and-white line contrasts.
Ideal for adding basic autonomy to robotics projects.
Whether you’re new to robotics or continuing to build on your previous projects, this video provides clear, step-by-step instructions to help you create a functional line-following robot. Get ready to take your 2WD robot to the next level!
