这是一个很有趣的结合arduino端口和processing端的实验。分为两个部分，arduino端将接口和电源口用导线连接；processing端口需要按照实际需要下载mini插件，再修改串口方可使用（方法简单，修改final String portName = Serial.list()[数字串口];中的数字串口为正在使用的arduino接口即可。实现效果为，当arduino导线连接时，processing会播放歌曲；导线断开，歌曲暂停(This is an interesting experiment that combines the Arduino port and the processing end. Is divided into two parts, Arduino terminal interface and power supply port is connected with the processing port; according to the actual need to download the mini plug-in, and then modify the serial port can be used to modify the final (simple method, portName = Serial.list (String) [digital] serial numbers in the serial port; Arduino interface is used to. The effect is that when the Arduino wire is connected, the processing will play the song; the wire is broken and the song is suspended)
