Build a line follower using an LM324N with a backup Arduino Nano.

Thank you for sharing your hard work. I appreciate how you designed your circuit board that sits right on top of chassis. It can be controlled just by Arduino and for anyone who wants to learn analog circuit design, you have included a simple comparator circuit that can totally control the robot without changing/swapping the sensors' and motors' pin. Yeah, some people might not understand and might have hard time understanding the board you designed but for people who truly want to start learning robotics/analog circuit design, this is a great place to start.
By the way, where do you order your boards from?
Thank you again.
