digitalWrite(LED_BUILTIN, LOW); 这会使 LED_BUILTIN 引脚恢复到 0 伏,然后关闭 LED。在开和关之间,设置足够的时间让我们看到电路变化,所以 delay() 该命令告诉Arduino在 1000 毫秒或一秒内什么都不做。当您使用delay()指令,在这段时间内没有其他任何事情发生。 了解基本示例后,请查看BlinkWithoutDelay示例以...

In the previous tutorial, we learned to blink LED by using the delay method. That method blocks Arduino from doing other tasks. In this tutorial, we are going to learn another method to blink LED without blocking other tasks. The detail instruction, code
