需求描述
儿子有一堆充电玩具，基本上都是锂电池，经常插上去充电忘了到时拔下来，所以需要一块能设置接通时间的插板以保障电池的安全。
硬件设计:
首先需要一块插板，接着需要一个继电器，然后采用arduino r3 uno 加 一个时钟模块来控制时间，最后配一个蓝牙模块，通过手机进行时间的设定。
时钟模块：DS3231 AT24C32， 采用I2C链接arduino板上 ，SCL->A5,SDA->A4,VCC->VCC,GND->GND。
蓝牙模块:HC-06, 使用用arduino的软串口，RXT->9,TXD->8,VCC->VCC,GND->GND，后来发现这款没蓝牙链接，会一直有报警，不知道能不能关，声音不大，但是挺烦的。
继续电器:220V 10A，3个脚那种，将公共端与常开端连入220V电源。
Arduino: R3 Uno 板，发现45块的山寨，还没25块的山寨好用，啥情况。
电源模块: 220VAC -> 5VDC ,用的是精密431那款，不小心摔了2下居然还能用，太意外，这里要吐槽下淘宝上卖android外接电源适配器的，没一个好用的，
有一个刚插上就烧的，太无良了。
辅助材料：扎带，胶水，PC板（用的是聚碳酸脂板，耐火，diy的东西安全重要啊），各种型号螺丝。
使用工具：这个是消费的大头，电烙铁（第一次使用是大学那个无良的电子社团，收了28块钱，结果就叫我进去用电烙铁拆了2个电容就没有任何音讯了，哥记住你了。。。），
电转，加各类转头（直接买了个360的电转工具箱），钢钜（拿来切割PC板，后来发现这个是本项目里最难的，昨天淘宝里定了330的切割机）
软件设计
arduino端：主要是串口接收手机发来的命令，并返回,代码如下：

android 端：
蓝牙操作部分是参考官方提供的蓝牙串口聊天室，蓝牙操作跟socket差不多，有个蓝牙串口服务协议（程序里体现就一段GUID)用来识别蓝牙链接提供的服务类型，一个标识吧了。
