一個基于python和pcduino的智慧校園系統，本著開(zhuang)源(bi)的精神可以用來借鑒。233。

運行在pcduino上的，需要搭配一些元件。

在程序的函數里已經寫的很詳細了。結合硬件，里面可以實現在線人臉識別，火災警報，太陽能充電控制，雨水收集灌溉，大屏幕控制，上放學語音燈控等功能。

p.s.上學鈴聲是個雙和弦的《小星星》，雖然歌很簡單，但是寫死我了-_-

至于像analog_read，digital_write，digital_read一類的函數還是需要根據嵌入設備型號自己寫的。

這個小程序是今天3月份全國創客競賽初中組特等獎的作品。個人覺得由此可見初中創客學生水平低下。勿噴。
