按按鈕才會發出聲音

void setup() {
  // put your setup code here, to run once:
  pinMode(8,OUTPUT);//pin8輸出(聲音)
  pinMode(2,INPUT_PULLUP);//pin2按鈕，輸入聲音
}
void loop() {
  // put your main code here, to run repeatedly:
  if(digitalRead(2)==LOW)tone(8,520,1000);//讀到2:按下去為LOW 在pin8輸出音頻520，一秒鐘
  else noTone(8);//不然pin8沒有音頻

}

按一個按鈕發出小蜜蜂

int Do=523;

int re=587;

int mi=659;

int fa=698;

int sol=784;

int song[13]={sol,mi,mi,fa,re,re,Do,re,mi,fa,sol,sol,sol};//宣告陣列

int now=0;//按按鍵的次數

bool up=true;

void setup() {

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

  pinMode(8,OUTPUT);

  pinMode(2,INPUT_PULLUP);

}

void loop() {

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

  

  if(up&&digitalRead(2)==LOW){

    tone(8,song[now],300);//發出陣列的聲音

    up=false;

    now=(now+1)%13;//讓數值可以重複播放

  }

  

  else {

    up=true;

  }

  delay(100);//因為會有雜訊所以要delay

  

}

用單芯線接地並插pin發出聲音
void setup() {
  // put your setup code here, to run once:
  for(int i=2;i<=13;i++){
    pinMode(i,INPUT_PULLUP);//讓所有燈亮
  }
  pinMode(8,OUTPUT);//發出聲音
}

void loop() {
  // put your main code here, to run repeatedly:
  if(digitalRead(2)==LOW)tone(8,523,200);
  if(digitalRead(3)==LOW)tone(8,587,200);
  if(digitalRead(4)==LOW)tone(8,659,200);
  if(digitalRead(5)==LOW)tone(8,698,200);
  if(digitalRead(6)==LOW)tone(8,784,200);
  if(digitalRead(7)==LOW)tone(8,880,200);
  if(digitalRead(9)==LOW)tone(8,988,200);
  if(digitalRead(10)==LOW)tone(8,1047,200);

}

自己連線自己
Client端
import processing.net.*;
Client client;
void setup(){
  size(200,200);
  client=new Client(this,"120.125.70.33",7777);//server端的IP
}
void draw(){
}
void mousePressed(){
  client.write("Irene is pretty");

}

Server端

import processing.net.*;

Server server;

void setup(){

  size(300,300);

  server=new Server(this,7777);

}

void draw(){

  Client thisClient=server.available();

  while(thisClient!=null){

    String now=thisClient.readString();

    if(now!=null) println("Server received:"+now);

  }

}
