  int x=analogRead(A0);

  tone(8,x);

  

}

用搖桿操控紅色的點

程式碼

import processing.serial.*;

Serial serial;

void setup(){

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

}

int x=512,y=512; 

void draw(){

  background(255);

  if( serial.available()>0){

    String now=serial.readString();

    String[] xy=splitTokens(now);

    x = int(xy[0]);

    y = int(xy[1]);

  }

  fill(255,0,0);

  ellipse(x,y,100,100);

}
