项目名称：树莓派3B（摄影水滴控制器的第二版（多线程控制四只电磁阀，带相机唤醒）
基本情况：GUI界面，设置五只电磁阀释放水滴以及间隔时间，控制闪光灯（四只）以及相机快门
软件工具：wxFormBuilder/wing 101/wxpython/gpio的python RPI.GPIO官方库0.6.2
使用wx.MilliSleep()，尝试毫秒级延时
threading--多线程控制，从第一版的单线程扩展，每个电磁阀以及闪灯、快门，一共8个线程，并行调度控制，同一个时间轴
硬件：RASPBERRY PI 3B//电磁阀五只，闪光灯四只，ULN2803 TLN-521-4
V0.23: 实现8个线程、同一时间轴控制四只电磁阀以及闪灯、快门，并且唤醒相机,五只电磁阀，实现两喷+三滴
