Hello . I am very interested in building line follower which I want to use it as maze solver .
However I experience some problem which my robot always go out of the line if I set it to high speed .
But if I turn it down it will lost too much speed . Therefore I have read your PID line follower in tutorial section .
But i am using my own PCB design IR sensor . So what I want to know is how do I set my set point for this particular case ?
And how do I read my current position ?
