 * @file main.c
 * @brief Battery Source Click Example.
 *
 * # Description
 * This example demonstrates the use of Battery Source Click board, 
 * by changing state of the output.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and disables the output.
 *
 * ## Application Task
 * Enabling output for 5 seconds, then disabling it for 5 seconds.
