if you have used different pins than I, you just need to modify those 2 lines. Also, in the future if you want to change the LED from pin 8 to pin 11 for example, you can modify this line without touching anything else in the code. ...

模拟,您可以看到 arduino nano 上的每个引脚如何能够单独控制我们立方体上的 LED。 使用Arduino Nano设计和构建4×4×4 Led Cube 检查所有 64 个 LED,确保它们使用小纽扣电池工作。 在我们开始组装 LED 立方体并进行任何焊接之前,最好确保 LED 正常工作。我们的 LED 需要 3.3 ...
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...
digitalWrite(13, LOW); //Step 3: Shut the LED off. //Something's missing here: The LED will immediately turn back on as there is no delay. } Carefully read each line and think about what it will do. This practice helps you to visualize what your code does, which makes it easier ...
