仿照小米台灯做一款智能台灯

学校电子电路设计大赛中有一题为设计一款智能台灯，思来想去想不出哪种外观比较好，最后决定copy一下雷总的台灯外观。

一、准备

智能台灯系统基于Arduino平台，采用两块ATmega8主控芯片，综合运用物联网技术、传感技术。
需要使用[贝壳物联](https://www.bigiot.net/)注册一个账号，获得设备id和APIKEY
将获得id和apikey填入master主机代码中对应位置

二、功能

实现自动调光功能，人来灯亮，人走灯灭（热释电传感器），并具有坐姿提醒功能，当使用者距离台灯太近时，台灯能及时产生提示。

能够实时显示时间和日期，并具有闹铃提醒功能。

能够检测环境温度和电池电量，并实时显示，在电量不足时能发出提示。

实现台灯定时开关。

可实现远程控制台灯亮灭，并能对亮度进行调整。

可实现对光的切换，如白光切换成暖光。

上述提醒功能均为语音提示，开关为触摸开关。

三、电路图

无线充电功能未在图上

四、使用方法

在贝壳物联客户端输入5位数字 10XXX 调节冷光亮度，XXX从0到255

20XXX 调节暖光亮度，XXX从0到255

3XXXX 同时调节冷光和暖光，XXX从0到255

4XXXX 闹钟功能，XXXX为24小时制时间

5XXXX 定时打开台灯，XXXX为24小时制时间

6XXXX 定时关闭台灯，XXXX为24小时制时

7000X 人体感应功能，X为1表示打开，0为关闭

五、3D模型

台灯全部采用3D打印，打印文件可以从这里下载

六、实物照片

手焊灯管，5个白色led，4个暖色led

整体外观

从左到右依次为触摸开关 oled屏幕人体感应器
