I am planning to place 2 line sensors on my robot project(ATmega8). I want to place LDR line sensors. Now i have a few questions.
What is the best distance to placethe sensors from each other? So that I have no bad readings and I still can follow the line 'smooth'.
What is the average breadth of a white line?
What is a good design of this type of sensor(LDR)? I would just place the LDR next to the led, is this okay?
And what is a good algorithme to use with a L293D with no pulse control(each motor is always on 100%)?
