I'm trying to develop a line detection sensor that basically sends back a TTL high signal when the sensor sees a line of a certain colour. I'll probably be using a white strip of insulation tape on a blue floor.

From the picture, it looks like a standard comparator circuit where the output level from the IR sensor is compared to a preset value from the trimmer.
