Overview

The 4 Channels Line Tracking modules provides an easy way for line tracking. A line sensor is composed of a number cells and each cell is composed of a sender and a receiver. The particularity of this sender/receiver pair is that it sends light that shall be reflected by the line to be detected but not by the eventually opaque background surrounding this line. Any sender/receiver pair that is able to make a difference between a line and the rest of ground (of a different color) can be used in a line sensor.
