架子撘起来了，但是手头只有2个舵机，没办法看到全貌。很是郁闷。分开测试，到是运行的挺流畅。
来个全家福
这个小孔改造的非常棒，和舵机可以实现无螺丝固定，而且配合很完美。
但愿舵机的轴都是这样。
组装很简单
摆拍一个。。那是马克笔，不是白板笔，如果写上了，就再也擦不掉了
少一个舵机，真是挠头
挥舞起来吧
用手持方式写了一个
猜了半天，才看明白，它写的是 00:02，那个零好圆哦
机架结构似乎还是不太合理，还有修改的余地。过几天弄个完美版的，淘宝开个店卖卖20￥一套预定送螺丝哦！
程序奉上，需要时间模块一个，我是用的DS3231，如果是其他时间模块，。H文件需要改一下。字模文件都是程序里写好的路径，如果感觉它的字实在太难看了，可以自己修改。呵呵
