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...
This can vary so you might need to change the values in the code to something that works better in your conditions (outside, inside, etc). A common problem is the light emitting from the red LED causes the light sensor to think that there is light. My best advice for this would be ...

Your electronics can now see in dazzling color with this lovely color light sensor. We found the best color sensor on the market, the TCS34725, which has RGB and Clear light sensing elements. An IR blocking filter, integrated on-chip and localized to the
Code – Reading BH1750 Ambient Light Sensor Copy the following code to your Arduino IDE. This code simply reads ambient light in lux and displays the values on the Serial Monitor. It is the example code from the library calledBH1750test(you can access it inFile>Examples>BH1750>BH1750test ...
In this tutorial, we will build an Arduino traffic light circuit. This project will involve using a a bit of code and a circuit.
