Arduino/讀取光敏電阻數值

使用範例/01Basics/AnalogReadSerial

CODE

// the setup routine runs once when you press reset:

void setup() {

  // initialize serial communication at 9600 bits per second:

  Serial.begin(9600);

}

// the loop routine runs over and over again forever:

void loop() {

  // read the input on analog pin 0:

  int sensorValue = analogRead(A0);

  // print out the value you read:

  Serial.println(sensorValue);

  delay(1);        // delay in between reads for stability

}

數值會與亮度成正比

從序列埠間視窗可以看到數值的變化，也可從serial plotter繪出圖表，當然也能用PLX-DAQ匯出資料到excel。

CODE

int analogPin = 0;

int RED = 0;

void setup(){

  Serial.begin(9600);

  Serial.println("CLEARDATA");

  Serial.println("LABEL,Time,Timer,RED");

      

}

void loop(){

      RED = analogRead(analogPin);

     

  Serial.print("DATA,TIME"); 

  Serial.print(",");

  Serial.print("TIMER"); 

  Serial.print(",");

  Serial.print(RED);

  Serial.print(",");

     

       delay(100);

}
