 * @brief Button 2 Click Example.
 *
 * # Description
 * This example demonstrates the use of Button 2 click board by toggling the button
 * LED and switch state on button press.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Toggles the button LED and switch state on button press and displays the state
 * on the USB UART.
