 * \brief IR reflect Click example
 * 
 * # Description
 * Example demonstrates the use of IR Reflect Click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enables - Start write log.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of IR Reflect Click board.
 * On this type of photointerrupter the infrared emitter and receiver are facing the same direction,
 * the infrared beam from the emitter gets bounced back to the receiver when an object 
 * is placed within the detecting range of the sensor ( optimal range is 3mm ).
 * These sensors are used to detect an object's presence or motion, such as a piece of paper passing through a printer
 * and counting when sensor is triggered.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * Data logs on usb uart when the sensor is triggered.
