using a LED and a light sensor. condition 1) If the sensor detects light, the LED will no longer be on. 2) If the sensor detects no light, the LED will be on. Here is the codes and demo. codes: /*/* Grove - Light Sensor demo v1.0 * * signal wire to A0. * By:http://w...
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...

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 ...
