網路時鐘 NODEMCU 應用

antlu

這是一個非常簡單的電路,一共只有三個零件組,LGC12002 兩個,NODMCU一個 !!
NODEMCU 網路搜尋一下,一大堆應用,價格 露天拍賣 約120元台幣,他透過家裡的網路分享器向相關網路校時的公司,提出時間需求,這一段資料我是從相關的網站之中COPY下來的,原創是用來驅動 LCM 搭配 溫溼度模組 DHT11來顯示時間溫度溼度,由程式裡面36000秒提出校時一次.希望大家喜歡!!

感謝 BEN CHENG 大提供的相關資料以及不斷的指導終於達到我的需求,當然也感謝許多同好的建議,甚至,遠在美國的丹丘大也提供寶貴意見... 首先我把問題的解決方法說明(因為我先前看過別人的資料但是不太懂),
1.先把 #include <DNSServer.h> //20190416
#include <ESP8266WebServer.h> //20190416
#include <WiFiManager.h>//20190416
WiFiManager wifiManager;//20190416 定義放到程式的頂端也就是 setup()之前.
2. 把 wifiManager.autoConnect("antlu"); 放在 setup()之內,這個作用就是 當你的作品移到"新的網路點"(先前的設定SSID PASSWORD 收不到的地方)上面時,你可以使用手機去搜尋到一個叫"antlu"的網路點.
3.把以前程式的指定 SSID 和 PASSWORD 去掉,沒有去掉會造成編譯錯誤喔!!
4.程式上傳完成 (可以比較我的先前程式差異.)
5.送電之後 時鐘不會顯示,原因是 程式要上網去抓取時間,但是WIFI 無法上網所以當然沒辦法走下去,其實這時候他正在等待設定...
6.使用 手機的找尋無線網路功能,找到 antlu 這個網點,經過一陣子之後就會顯示 照片1 的畫面.


7. 選擇第一項 configure WiFi 進入照片2 的畫面.


8. 在畫面上就有許多 網點可以讓你選擇,選取你可以有密碼的網點,然後輸入密碼,記得按下 SAVE !

9. 這時候會跳出 照片3 的畫面.


10.沒多久之後 時鐘會顯示了 照片4 ,也就是成功了!!


心得: WiFiManager 功能太強了! 因為習慣領域的關係,我一值把它想的非常複雜,其實,真的很簡單,這是我對網路 和 無線網路的知識極其缺乏的原因... 再次感謝 BEN CHENG 大,別忘了給我訊息 我要把 LGC12002 寄給你!!
