 * \brief OneShot Click example
 * 
 * # Description
 * This example shows the user how to configure and use the One Shot Click. The Click has a 
 * monostable monovibrator which cam generate a pulse of width between 1μs and 33.6 seconds. 
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the logger and Click modules. Resistance data,
 * acquired from the AD5241, is displayed at the end of the initialization process. 
 * 
 * ## Application Task  
 * This function triggers one shot every 8 seconds.
