Sensor selection, interface, and data interpretation


In this task, we will discuss the different sensors available to build a line following robot and pick a sensor for this project.

Engage thrusters

We will discuss three sensors in this task, including light detecting resistors, IR emitters/detectors, and a camera. We will discuss their operations, features, and their distinct edge over other sensing techniques as well as their disadvantages.

Light Dependent Resistors

As the name suggests, Light Dependent Resistors are those that change their resistance when light is incident on the surface of the resistor.

Light Dependent Resistors are used in combination with a bright LED. We can make use of the difference in reflectivity between different coloured surfaces to follow a black line on a dark surface.

When Light Dependent Resistor is inserted into a potential divider configuration, as shown in the following diagram, the drop in voltage causes a potential imbalance leading to a change in voltage...
