LED变色吊灯

第5步编程

我给LED灯从外向内进行编号，其中1,3,5,7,9,11 有公共的红、绿、蓝总线（即所有的红线接在一起形成A总线），2,4,6,8,10,12有共同的绿、红、蓝总线（B总线）。

然后把LED的共阳极线和总线按照下面的方式连接到 arduino 。

LED1阳极= 0;
LED2阳极= 1;
LED3阳极= 2;
LED4阳极= 4;
LED5阳极= 7;
LED6阳极= 8;
LED7阳极= 12;
LED8阳极= 13;
LED9阳极= 14;
LED10阳极= 15;
LED11阳极= 16;
LED12阳极= 17;
红色总线 A = 3;
绿色总线 A = 5;
蓝色总线 A = 6;
红色总线 B = 9;
绿色总线B = 10;
蓝色总线B = 11;
