 * 
 * =====================功能说明=====================
 * 使用Arduino Uno开发板通过FASTLED库控制WS2812光带。
 * 使用fill_palette函数通过用户自定义色板点亮LED光带。
 * 
 * 本示例程序需要Arduino第三方库FastLED。如有需要，可通过以下链接下载该库:
 * http://www.taichi-maker.com/homepage/download/#library-download
 * 
 * 如需了解如何为Arduino IDE安装第三方库，请参见以下链接地址的视频教程：
 * http://www.taichi-maker.com/homepage/reference-index/arduino-library-index/install-arduino-library/
 *  
 * =====================电路连接======================
 * 此示例程序中，Arduino输出控制信号引脚为9号引脚。
 *
