Blinking an LED is great, as you learned in the preceding chapter, but what makes the Arduino microcontroller platform so useful is that the system is equipped with both inputs and outputs. By combining both, your opportunities are nearly limitless. For example, you can use a magnetic reed s...

37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
55、阻抗的状态.配置为INPUT的引脚可以理解为引脚取样时对电路有极小的需求,即等效于在引脚前串联一个100兆欧姆(Megohms)的电阻。这使得它们非常利于读取传感器,而不是为LED供电。引脚(Pins)配置为输出(Outputs)引脚通过pinMode()配置为输出(OUTPUT)即是将其配置在一个低阻抗的状态。这意味着它们可以为电路提供充足...
