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.
pinMode(ledPin, OUTPUT);// 将LED引脚设置为输出模式 pinMode(sensor,INPUT);// 将传感器引脚设置为输入模式 Serial.begin(9600);// 打开串口通信,用于调试 } voidloop() { intsensorValue = analogRead(sensorPin);// 读取光线传感器的数值 intsensorin = digitalRead(sensor);// 读取传感器引脚的状态(高电...
首先，通过“import time”和“from pinpong.board import Board,Pin”语句，导入time和pinpong库模块；“Board("uno").begin()”语句的作用是实现对Arduino uno板型的初始化操作（包括连接主板端口号的自动识别）；接着，分别建立led、SoundSensor和LightSensor三个变量，分别对应LED灯、声音传感器和光线传感器的声明...
