Arduino程式碼:

void setup() {

  for(int i=2; i<=13; i++){

      pinMode(i, OUTPUT);

  }

   Serial.begin(9600);

}

void loop() {

  // put your main code here, to run repeatedly:

  int now=analogRead(A0);

  int level = now/4;

  for(int i=2; i<=13; i++){

      if(i<level) digitalWrite(i, HIGH);

      else digitalWrite(i, LOW);

  }

  Serial.write(level);

  delay(20);

}

Processing程式碼:

import processing.serial.*;

Serial myPort;

void setup(){

    size (765,100);

    myPort = new Serial(this, "COM3", 9600);

}

int level=0;

void draw(){

    background(255);

    fill(255,0,0);

    rect(0,0, level*5, 100);

    if(myPort.available()>0) {

        int now = myPort.read();

        level = now;

  }

}
