• 組裝:
• SW  -  pin2
• GND  -  GND
• +5V  -  5V

Arduino v.s Processing

• Arduino
• void setup() {
•   // put your setup code here, to run once:
•   Serial.begin(9600);
•   pinMode(2,INPUT_PULLUP);
•   pinMode(8,OUTPUT);
• }
• int state=0;
• void loop() {
•   // put your main code here, to run repeatedly:
•   if(digitalRead(2)==LOW && state==0){
•     state=1;
•     Serial.write("1");
•   }
•   if(digitalRead(2)==HIGH && state==1){
•     state=0;
•     Serial.write("0");
•   }
•   delay(100);
• }
• Processing
• import processing.serial.*;
• Serial myPort;
• void setup() 
• {
•   size(200, 200);
•   myPort = new Serial(this,"COM4",9600);
• }
• int btn=0;
• void draw() {
•   if(myPort.available()>0){
•     int now=myPort.read();
•     if(now=='1') btn=1;
•     else btn=0;
•   }
•   if(btn==1) background(200,100,255);
•   else background(255);

連線到老師的電腦~(多人連線)

• 載入外掛

• Processing(客戶端)
• import hypermedia.net.*;//外掛
• UDP udp;
• void setup(){

•   udp = new UDP(this,6000);
•   udp.send("hello world","120.125.70.53",6100);
• }
• void draw(){}
• void mousePressed(){
•   udp.send("mousePressed","120.125.70.53",6100);
