下面的代码用一个for()循环开始来设计数字引脚pin2-7作为6个LED灯的输出。 在代码的主循环里,两个for()循环用来逐渐循环LED灯,一个接一个,从pin2-7。一旦pin7被点亮,程序就会反过来,倒着点亮每一个LED灯。 /* For Loop Iteration Demonstrates the use of a for() loop. Lights multiple LEDs in sequence...

其主要应用领域有LED全彩发光字灯串,全彩LED模组,LED像素屏,各种电子产品,电子设备跑马灯等。WS2812最牛的地方除了内部包含了智能数字接口数据锁存信号整形放大驱动电路和高精度内部振荡器外,还采用了单线归零码的通讯方式:每个WS2812在上电复位以后,DIN端接收从控制器传输过来的数据,首先送过来的24bit数据被第一个WS28...

LED lights go gradually brighter and then gradually dimmer, demonstrating breathing effects. 4.Program analysis In the main program, we set the variable i to 0 as an initial value. Although the default system value is already 0, but we still did it just to develop a good habit when we c...
