仿照小米檯燈做一款智能檯燈

學校電子電路設計大賽中有一題為設計一款智能檯燈，思來想去想不出哪種外觀比較好，最後決定copy一下雷總的檯燈外觀。

一、準備

智能檯燈系統基於Arduino平台，採用兩塊ATmega8主控晶元，綜合運用物聯網技術、感測技術。

需要使用[貝殼物聯](https://www.bigiot.net/)註冊一個賬號，獲得設備id和APIKEY

將獲得id和apikey填入master主機代碼中對應位置

二、功能

實現自動調光功能，人來燈亮，人走燈滅（熱釋電感測器），並具有坐姿提醒功能，當使用者距離檯燈太近時，檯燈能及時產生提示。

能夠實時顯示時間和日期，並具有鬧鈴提醒功能。

能夠檢測環境溫度和電池電量，並實時顯示，在電量不足時能發出提示。

實現檯燈定時開關。

可實現遠程控制檯燈亮滅，並能對亮度進行調整。

可實現對光的切換，如白光切換成暖光。

上述提醒功能均為語音提示，開關為觸摸開關。

三、電路圖

無線充電功能未在圖上

四、使用方法

在貝殼物聯客戶端輸入5位數字 10XXX 調節冷光亮度，XXX從0到255

20XXX 調節暖光亮度，XXX從0到255

3XXXX 同時調節冷光和暖光，XXX從0到255

4XXXX 鬧鐘功能，XXXX為24小時制時間

5XXXX 定時打開檯燈，XXXX為24小時制時間

6XXXX 定時關閉檯燈，XXXX為24小時制時

7000X 人體感應功能，X為1表示打開，0為關閉

五、3D模型

檯燈全部採用3D列印，列印文件可以從這裡下載

六、實物照片
