 * @brief 1x4 RGB Click example
 *
 * # Description
 * This example demonstrates the use of the 1x4 RGB Click board
 * by controlling the color of the LEDs [LD1-LD4].
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C module and log UART.
 * After driver initialization, the app executes a default configuration.
 *
 * ## Application Task
 * The demo example shows the color change of four RGB LEDs, 
 * starting with red color, through green and blue, and ending with white.
 * These LEDs actually consist of three single-colored LEDs 
 * (Red-Green-Blue) in a single package. 
 * Various colors can be reproduced by mixing the intensity of each LED.
