 * \brief UV Click Driver Example
 *
 * # Description
 * This is a example which demonstrates the use of UV Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Configuration of the Click and log objects.
 *
 * ## Application Task
 * Reads the result of AD conversion once per second and calculates
 * the UV index based on that. Results are being sent to the USB UART
 * where you can track their changes.
