第一步:(可以按出單音do,re,mi)

程式碼:

int Do=523;

int Re=587;

int Mi=659;

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(digitalRead(2)==LOW) tone(8,Mi,1000);

  else noTone(8);

}

第二步:(同鍵按出不同音)

程式碼:

int Do=523;

int Re=587;

int Mi=659;

int song[9]={Do,Re,Mi,Do,Do,Re,Mi,Do,Mi};

int now=0;

bool UP=true;

void setup() {

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

  pinMode(8,OUTPUT);

  pinMode(2,INPUT_PULLUP);

}

void loop() {

  if(UP&&digitalRead(2)==LOW){

    tone(8,song[now],100);

    UP=false;

    now=(now+1)%9;

  }

  else{

    UP=true;

  }

  delay(1000);

}

void setup() {

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

  for(int i=2;i<=13;i++){

    pinMode(i,INPUT_PULLUP);

  }

    pinMode(8,OUTPUT);

}

第三步:(用電線彈奏音樂)

程式碼:

void loop() {

  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(8,689,200);

  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); 

}

第四步:(Client端連接Server端)

Client端程式碼:

import processing.net.*;
Client client;
void serup(){
   size(200,200);
   client=new Client(this,"120.125.70.41",7777);
}
void mousePressed(){
   client.write("Hello");
}

Server端程式碼:

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);  

 }

}
