   VERSION: 0.1

This is a simple example of how to use the HobbyComponents Arduino 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.

You may copy, alter and reuse this code in any way you like but please leave 
reference to HobbyComponents.com in your comments if you redistribute this code. */
