请问这段小爱同学的示例代码控制的rgb是8266的哪几个引脚？
https://github.com/blinker-iot/blinker-library/blob/master/examples/Blinker_MIOT/MIOT_LIGHT/MIOT_LIGHT.ino这段示例代码里面也没有注释，研究了3天实在是看不懂啊，只会开关和调亮度

求大神帮忙加注释，主要是控制的哪三个引脚？
这段代码是控制共阴极rgb的吧？
#define PIN 2 edayer 发表于 2020-2-12 16:30
#define PIN 2
rgb应该3个引脚啊
RGB是1个信号脚，3个脚分别是VCC，GND，DAT。。。。。去度以下ws2812就知道了 WS2812用了2脚，还用了个LED脚，但是不明白14，15脚是干嘛的？
