iPhone控制的简易物联网

第8步启动程序

1. 如果你没有processing IDE，需要先下载，地址是：processing.org.

  2.你还需要下载 oscP5 library，地址是：http://www.sojamo.de/libraries/oscP5/#installation
    解压文件，将oscP5文件夹移动到目录 {C:\Users\[your user name]\Documents\Processing\libraries\}

  3. 打开附件的代码运行。      
     Processing IDE运行方式和 Arduino IDE一样：File->open

   4. 在Arduino IDE上为Arduino板选择COM接口，记住你的数字
    Tools-> serial port-> COM?

   5  

退出IDE并 " 在" arduinoPort = new Serial(this, "COM4", 9600)" 中改变"COM4的值，变为上一步看到的Arduino序列端口。
