 * @brief Relay 4 Click Example.
 *
 * # Description
 * This example demonstrates the use of Relay 4 Click board by toggling the relays state.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Switches the relays 1 and 2 state every 5 seconds and displays the state on the USB UART.
