Line Follower

grabcad

I've been fascinated by line following robots since my high school days, and I wanted to create a simple one for someone new to robotics to learn from. I already have a similar project on my Hackster profile (https://www.hackster.io/ajayadahal1000/simple-line-follower-813573), which uses an Arduino Uno and L293D motor driver. This project is different, though, because I've combined two circuit boards to make it unique. A jumper cap allows you to switch between the analog circuit and the Arduino Nano, making it easy to learn both analog circuits with LM324N comparators and digital electronics programming using Arduino. By combining these two circuits, you can take control of a situation if something goes wrong in the analog circuit – simply switch to the Arduino side to continue participating. I've included all the necessary files, and the board design was done in KiCad. Some 3D models were obtained from GrabCad and other websites. If you need help or have questions, just comment below!
