 * @brief Relay 6 Click example
 *
 * # Description
 * This example demonstrates the use of Relay 6 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 all relays state every second and displays the state on the USB UART.
