發出很長的聲音

程式碼:

void setup() {

  pinMode(13,OUTPUT);

  pinMode(8,OUTPUT);

}

void loop() {

  int now = analogRead(A0);

  tone(8,now);

}

控制搖桿能讓燈亮

程式碼:

void setup() {

  for(int i=2; i<=13; i++){

    pinMode(i,OUTPUT);

  }

}

void loop() {

  int now = analogRead(A0);//0...511

  int level = now/ (512/13);

  for(int i=2;i<=13;i++){

    if(i<level)digitalWrite(i,HIGH);

    else digitalWrite(i,LOW);

  }

}

跑字

程式碼:

void setup() {

  for(int i=2; i<=13; i++){

    pinMode(i,OUTPUT);

  }

  Serial.begin(9600);

}

void loop() {//1000Hz太快

  int now = analogRead(A0);//0...511

  int level = now/ (1024/13);//01234...13

  for(int i=2;i<=13;i++){

    if(i<level)digitalWrite(i,HIGH);

    else digitalWrite(i,LOW);

  }

  Serial.write(('A'+level));

  delay(100);//1000/100=10fps

}

控制搖桿能讓色塊移動

程式碼:

import processing.serial.*;

Serial myPort;

void setup(){

  size(765,100);

  myPort = new Serial(this,"COM5",9600);

}

int level=0;

void draw(){//60fps

  background(255);

  fill(255,0,0);

  rect(0,0,level*3,100);

  if(myPort.available()>0){

    int now = myPort.read();//0...255

    level = now;

  }

}
