I have some experiment on line following robot for the ABU robo contest. But with AVR. It's easy, too. Hope I can help you. dangson302(at)gmail.com
 

Here is a line follower.

Hi, I am struggling with getting the threshold voltage (reference voltage) for the sensors to suite the pic16f887 to recognize as logic zero and logic 1. I am using SENSOR HOA0709-1 with comparator to microcontroller.
I have threshold voltage of 1.6v for white surface and 3.6v for black surface; this does not do any effect as I programmed it to be.
