discussion thread on line following using two light sensors @http://forums.usfirst.org/showthread.php?p=30889

Another fun exercise that helps bring a "physical manifestation" to the abstract idea of light levels is to add in the light sensor blocks inside each switch line and connect sound blocks with the volume control to the light levels. The sound made by the robot then oscillates depending on how well it's tracking and provides an auditory feedback for the student.
