Well, I can't guarrantee this works, but if you want to look at it...
PHP Code:
// Check if the right sensor is reading the line
if(lineDetectorLeft == ON_LINE)
{
// Turn right
driveMotorLeft = 127;
driveMotorRight = 254;
}
else if(lineDetectorRight == ON_LINE)
{
// Turn left
driveMotorLeft = 254;
driveMotorRight = 127;
}
else
{
// Go forward
driveMotorLeft = 254;
driveMotorRight = 254;
}
Subsitute pwmXX for the driveMotorLeft and Rights, the lineDetectorLeft and Rights with the digital inputs they are on, and the ON_LINEs with the value that the sensors read when over the line. This is a very simple algorithm and can be improved, but it gives you the idea. Put it in its own function and continually call it and it will (should) faithfully follow a line.
--EDIT--
You can also adjust the speeds passed to the motors. The way it is now, it might lose the line because it is too fast.
