 * @brief Tester 2 Click Example.
 *
 * # Description
 * This example demonstrates the use of Tester 2 Click board by controlling all
 * LEDs on the Click board together and in sequential pin toggling with different delays.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Toggles all pins together 5 times with a 500ms delay between each toggle, then toggles
 * each pin sequentially with a 300ms delay between toggling each pin.
