pinMode(2, OUTPUT)- 在使用Arduino的一个引脚之前,你需要告诉Arduino Uno R3它是INPUT还是OUTPUT。 我们使用一个名为pinMode()的内置“函数”来执行此操作。 digitalWrite(2, HIGH)- 当您使用引脚作为OUTPUT时,您可以将其命令为HIGH(输出5 V)或LOW(输出0 V)。 结果(Result) 您应该看到LED打开和关闭。 如果...

LED是用于许多不同应用的小型强光灯。首先,我们将学习闪烁LED,即微控制器的Hello World。它就像打开和关闭灯一样简单。建立这个重要的基线将为你提供坚实的基础,以实现更复杂的实验。 必需的组件 你将需要以下组件: 1× Breadboard 面包板 1× Arduino Uno R3 ...
pinMode(2, OUTPUT) − Before you can use one of Arduino’s pins, you need to tell Arduino Uno R3 whether it is an INPUT or OUTPUT. We use a built-in “function” called pinMode() to do this.digitalWrite(2, HIGH) − When you are using a pin as an OUTPUT, you can command ...
