Hello,
I want to make fastest line following robot using arduino with PID algorithm.Sensor can be either LDR or IR.
Please can anyone send me full detail of this project.
thanks
You don't want to spend any money buying commercial products that other people might have used in developing a line following robot, and yet you expect others to give you code that will work with your homemade sensors. Pigs want to fly, too.
Well, I would suggest starting here for PID and Arduino:

The second link is an excellent write up on a PID implementation.
I messed around with line followers a while back. There is link below to what I managed to put together. No PID and definitely not the fastest out there, so you will need to beat it by a wide margin:
