照明燈：上面的燈

夜燈：里面的燈

1、運(yùn)行：插上電就自動(dòng)運(yùn)行了~~

2、兩種運(yùn)行模式：

1)自動(dòng)模式，在這個(gè)模式下，可以自動(dòng)感應(yīng)人體，感應(yīng)到人體后，照明燈自動(dòng)點(diǎn)亮，延時(shí)一段時(shí)間后關(guān)閉。

2）手動(dòng)模式，就是不會(huì)自動(dòng)感應(yīng)人體，完全依靠按鍵和手機(jī)控制。

開(kāi)機(jī)默認(rèn)進(jìn)入自動(dòng)模式，按鍵長(zhǎng)按2s切換模式，進(jìn)入手動(dòng)模式（當(dāng)進(jìn)入手動(dòng)模式的時(shí)候，板子上綠色的指示燈會(huì)亮）

按鍵：兩個(gè)按鍵，突出的那個(gè)是控制按鍵，凹下去的那個(gè)是復(fù)位按鍵，相當(dāng)于重啟。

控制按鍵：?jiǎn)螕?/span>-照明燈開(kāi)關(guān)。雙擊-夜燈開(kāi)關(guān)（雙擊按兩下之間的時(shí)間間隔要小于0.4s）。長(zhǎng)按-模式切換。

使用步驟：

1，在手機(jī)設(shè)置里打開(kāi)藍(lán)牙，搜索設(shè)備，配對(duì)（藍(lán)牙設(shè)備名稱為DJ`s Light，配對(duì)密鑰1234或者0000）

2、配對(duì)完成后打開(kāi)APP，點(diǎn)擊列表里的設(shè)備就可以自動(dòng)連接，然后進(jìn)行相應(yīng)的控制操作

1、最上面textview顯示藍(lán)牙狀態(tài)

下面依次是藍(lán)牙開(kāi)關(guān)，如果藍(lán)牙打開(kāi)，listview里會(huì)顯示已配對(duì)并且可用的設(shè)備。點(diǎn)擊就可以連接，連接成功會(huì)有提示，然后就可以進(jìn)行控制。

2、Lighting light：照明燈開(kāi)關(guān)

3、Night light：夜燈開(kāi)關(guān)

4、手動(dòng)模式：手動(dòng)模式/自動(dòng)模式切換開(kāi)關(guān)，成功會(huì)返回 “success！”。

5、延時(shí)關(guān)閉時(shí)間：自動(dòng)模式下照明燈感應(yīng)到人體開(kāi)啟后延時(shí)關(guān)閉的時(shí)間。手動(dòng)模式下失效。成功會(huì)返回 “success！”。

6、定時(shí)關(guān)閉時(shí)間：可以設(shè)置照明燈在某個(gè)時(shí)間后關(guān)閉（大于等于1分鐘，小于24小時(shí)-1440分鐘）成功會(huì)返回 “success！”。
