hi,
i have been trying to search on how to start with a line follower,(this is my first step in robotics)but i have not been able to learn much. I dont have any access to kits...
So can anyone tell me how i can start off,i have read that comparator circuit can be used to employ line following..i wud like to use this method.
Can anyone help me,as to where i can learn to make one,or wud u advise that i start experimenting on my own ,is that the way to learn??

 

I'm just read something about it at:
