This is a simple example of how to use the Hobby Components line hunting sensor 
module (HCARDU0005). It is a very simple module that requires only one DIO
pin (defined as an input) to operate. When the sensor detects a reflective object 
in close proximity it will pull a DIO pin that it has been connected to LOW. A 
non reflective or no object in close proximity will cause the DIO pin to go high.
