 * @brief POT 5 Click Example.
 *
 * # Description
 * This example demonstrates the use of POT 5 Click board by reading and displaying
 * the potentiometer position.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Reads and displays on the USB UART the potentiometer position in forms of voltage and
 * percents once per second.
