原本預設

程式碼:

void setup() {

  // put your setup code here, to run once:

  pinMode(2,INPUT_PULLUP);//Step01:讓第2個腳,可以收資料

  pinMode(8,OUTPUT);//Step02:Buzzer

}

void loop() {

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

  if(digitalRead(2)==LOW) tone(8,572,100);

  else noTone(8);

}

把聲音關掉,變成送USB

程式碼:

void setup() {

  Serial.begin(9600);//USB連結

  pinMode(2,INPUT_PULLUP);//Step01:讓第2個腳,可以收資料

  pinMode(8,OUTPUT);//Step02:Buzzer

}

int state=0;//0:not pressed, 1:pressed

void loop() {

  if(digitalRead(2)==LOW && state==0){

    state=1;//按下去

    Serial.write("1");

  }

  if(digitalRead(2)==HIGH && state==1){

    state=0;//換成沒按

    Serial.write("0");

  }

  delay(100);//慢0.1秒

}

按按鈕~可變色~

程式碼:

import processing.serial.*;

Serial myPort;

void setup(){

  size(300,200);

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

}

int button=0;

void draw(){

  if(myPort.available()>0){//有資料等你收喔!

  int now = myPort.read();

  println("現在你讀的其實是:"+now);

  if(now == '1') button=1;

  else button=0;

 }

 if(button==1) background(255,0,0);

 else background(255);

}

突破老師的電腦

1.先安裝(如圖)

2.

程式碼:

import hypermedia.net.*;

UDP udp;

void setup(){

  size(300,200);

  udp = new UDP(this, 6000);

  udp.send("hello world","120.125.70.53",6100);

}//不重要訊息啦 

void draw(){

  

 }

void mousePressed(){

  udp.send("hello world","120.125.70.53",6100);

}
