一个基于python和pcduino的智慧校园系统，本着开(zhuang)源(bi)的精神可以用来借鉴。233。
运行在pcduino上的，需要搭配一些元件。
在程序的函数里已经写的很详细了。结合硬件，里面可以实现在线人脸识别，火灾警报，太阳能充电控制，雨水收集灌溉，大屏幕控制，上放学语音灯控等功能。
p.s.上学铃声是个双和弦的《小星星》，虽然歌很简单，但是写死我了-_-
至于像analog_read，digital_write，digital_read一类的函数还是需要根据嵌入设备型号自己写的。
这个小程序是今天3月份全国创客竞赛初中组特等奖的作品。个人觉得由此可见初中创客学生水平低下。勿喷。
