 * \brief Relay 3 Click example
 * 
 * # Description
 * This example starts off with the initialization and configuration of the click and logger
 * modules and later on showcases how to turn specified relays ON/OFF using the output pins. 
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initialises and configures the logger and click modules.
 * 
 * ## Application Task  
 * This function turns on the 1st and the 2nd relay and then turns them both off.
