 * \brief Ambient5 Click example
 * 
 * # Description
 * This application calculates the ambiance light. 
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes i2c driver, powers the device and calculates refresh time.
 * 
 * ## Application Task  
 * Logs high resolution data after a period of time ( refresh time calculated using - ambient5_getRefreshTime( ) )
