 * @brief SolidSwitch Click example
 *
 * # Description
 * This example demonstrates the use of SolidSwitch click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger and enables the click board.
 *
 * ## Application Task
 * Enables different outputs every 3 seconds and displays all enabled 
 * outputs on USB UART.
