RAM Electronics's Description
The Line Follower sensor is an add-on for your robot project that gives your
robot the ability to detect lines or nearby objects. The sensor works by
detecting reflected light coming from its own infrared LED. By measuring the
amount of reflected infrared light, it can detect transitions from light to
dark (lines) or even objects directly in front of it.
