Question

Recently, I was working on a Line Following Robot and Hopefully I completed it too. But, I want to integrate PID in it's program sketch.

Can anyone help me out here about what is PID and what's the best way to learn it?

I made a post about using PID on Element14 here: https://www.element14.com/community/community/arduino/blog/2020/01/06/simple-arduino-dc-motor-control-with-encoder-part-2

At the bottom of the post are some useful links including a well documented Arduino PID library. Below my post in the comments is a link to work by Jan Cumps that describes his C code for PID based on the library.

If you google Arduino PID controller, you get a lot of hits, including many Videos. This one looked particularly useful: https://www.youtube.com/watch?v=crw0Hcc67RY
