打开"LightSensor.h"文件,并在类定义的结尾添加以下代码: intgetMaxValue(); 1. 这将在类中添加一个公共函数"getMaxValue",用于获取光线传感器的最大值。 然后,打开"LightSensor.cpp"文件,找到类定义的结尾,并在类实现的开头添加以下代码: intLightSensor::getMaxValue(){// 在此处添加获取最大值的代码} 1...
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...

奥地利物理学家,数学家和天文学家多普勒,克里斯蒂安·安德烈亚斯(Doppler · Christian Andreas)1803年11月29日出生于奥地利的萨尔茨堡 (Salzburg)。1842年,他因文章 "On the Colored Light of Double Stars" 、“多普勒效应”(Doppler Effect),而闻名于世。1853年3月17日,多普勒与世长辞。
You can also move the second line of code to the ‘loop’ function so that it will be executed repeatedly and keep transmitting it. This is useful if you are monitoring something in real time such as voltage or a sensor reading.You should see the ‘TX’ light on your Arduino blink ...
