Line Follower Kit
A line follower consists of an infrared light sensor and an
infrared LED. It works by illuminating a surface with
infrared light; the sensor then picks up the reflected
infrared radiation and, based on its intensity, determines
the reflectivity of the surface in question. Light-colored
surfaces will reflect more light than dark surfaces, resulting
in their appearing brighter to the sensor. This allows the
sensor to detect a dark line on a pale surface, or a pale line
on a dark surface.
You can use a line follower to help your robot navigate along
a marked path, or in any other application involving
discerning the boundary between two high-contrast surfaces.
A typical application uses three line follower sensors,
such that the middle sensor is over the line your robot is
following.
