Reads an analog input on pin 0, converts it to voltage, and prints the result to the Serial Monitor. Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu). Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground. ...
intanalogPin = A0;// 选择模拟引脚A0intsensorValue;voidsetup(){ Serial.begin(9600); }voidloop(){ sensorValue = analogRead(analogPin); Serial.println(sensorValue); delay(100); } 在这个示例中,在setup()函数中初始化串口通信,波特率为9600。然后在loop()函数中,通过analogRead(analogPin)读取模拟引脚...
