 * @brief 2x4 RGB Click Example.
 *
 * # Description
 * This example demonstrates the use of 2x4 RGB click board by cycling through
 * a set of colors, gradually increasing the brightness of each LED in a sequence,
 * and then decreasing the brightness before moving on to the next color in the array.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration which sets
 * the LEDs brightness and current gain to a minimum and the color to black (all LEDs off).
 *
 * ## Application Task
 * Cycles through a set of colors, gradually increases the brightness of each LED
 * in a sequence, and then decreases the brightness before moving on to the next
 * color in the array. The current color's name and RGB value are logged to the USB UART.
