Line Follower using Arduino C https://drive.google.com/file/d/1qqULa5GYlIyCNqTbSHa-biF04TpGwHrB/view?usp=sharing
Required Parts to build the robot are as follows: • Chassis (including motors and wheels ) • Arduino Uno r3 • L293D Motor Shield • IR Proximity Sensors (pair) • Jumper Wires • Switch • 4AA Battery Holder
Working Steps First, I collect all the components I need. Then, I learned how to build the car and finished it first. Then, I started searching for how to connect the components and connected them after. And then started coding; During this stage, I encountered several problems such as: 1- In the first one, I was running the robot with one IR sensor: This enables the robot to move forward and stop only, and it is Inaccurate in determining the line it will walk on. To solve this, I made it works with two sensors : Which enables the robot to move forward, right, left, and stop ( which is our target). 2- In the second one: The wheels spin properly as we want them to, But when they are placed on the track, They can't move. To solve this: After researching, I came up with several possibilities, And I had worked on fixing this issue, Which made the robot work as intended.
