本文實現(xiàn)Arduino UNO R3通過ESP8266-01模塊連接機智云平臺，從而實現(xiàn)用手機APP遠(yuǎn)程點亮LED燈。

ESP8266模塊本地調(diào)試

1

當(dāng)我們參考機智云官網(wǎng)給的教程時，關(guān)于Arduino平臺主要都是關(guān)于機智云官方自己的開發(fā)板Gokit的資料。但當(dāng)我們只使用Arduino UNO R3接入機智云平臺，有很多教程通過添加了兩個按鍵來選擇airlink和softap模式，其實我們只要在本地給ESP8266配好了網(wǎng)絡(luò)連接，就不需要每次通過按鍵切換配網(wǎng)模式。

第一步：首先在官網(wǎng)下載機智云固件GAgent,

第二步：使用ESP8266下載工具ESPFlashDownloadTool，將固件下載至ESP8266中。

第三步：在機智云官網(wǎng)下載機智云串口調(diào)試助手,

將ESP8266通過串口轉(zhuǎn)USB工具插在電腦上，安裝好驅(qū)動，選擇中確的驅(qū)動后，打開串口，填入在官網(wǎng)申請的product_key和Product Secret后，就能在右邊看見數(shù)據(jù)點了，此時再打開指令界面，點擊AirLink命令，ESP8266就進(jìn)入了自動配網(wǎng)模式；

第四步：下載機智云移動端APP

打開APP,點擊一鍵配置，輸入家里的WiFi賬號及密碼，選擇樂鑫，因為剛才我們已經(jīng)將ESP8266設(shè)置成AirLink透傳模式，現(xiàn)在通過APP就可以將家里的WiFi信息發(fā)送給ESP8266,此時APP發(fā)現(xiàn)新設(shè)備下會出現(xiàn)你的WiFi模組，點擊后就會看到你定義的數(shù)據(jù)點了。

硬件搭建

2.1硬件連接圖

LED接上220歐姆電阻，連在Arduino的D4上，ESP8266CH-PD和vcc都接高電平。

注意：

在給Arduino燒錄程序的時候要斷開ESP8266與Arduino的串口連接，否則會有干擾導(dǎo)致代碼燒錄不成功；

ESP8266-01只能供給3.3v電壓，5v電壓可能會燒壞WiFi模組
