ESP32 NTP Timer with WS2812B

        之前都是透過RTC 時鐘去設定時間後，再從RTC時鐘模組去取得時間，這次為了減少模組的使用，我們透過連線有線網路後去取得NTP時鐘，理由嗎，減少時間誤差，有些時候運作久了時間就會跑掉，話不多說Let's start!

前置作業

一、準備材料

開發板：ESP32 NodeMCU 

模　組：WS2812B 時鐘模組(文章連結)


 

開發環境 

Arduino IDE

Library  WS2812FX.h 連結https://github.com/kitesurfer1404/WS2812FX 

二、電路接線


步驟說明

步驟一、電路接線

請依照電路接線完成

步驟二、安裝WS2812FX Library

參考這篇 連結 https://850121.blogspot.com/2022/03/arduino-ws2812b.html

步驟三、複製程式

Git 連結 https://github.com/windyman24/ESP32-NTP-Timer-with-WS2812B

步驟四、編譯並上傳


  1. #include "WS2812FX.h"
  2. #include "WiFi.h"
  3. #include "time.h"
  4. const char* ssid = "Your Wifi SSID";

  6. //NTP Time
  7. int timezone = 8 * 3600;//Set Time zone ,In Taiwan is +8, so Time zone is 8 * 3600
  8. int dst = 0;
  9. time_t now = time(nullptr);
  10. struct tm* p_tm = localtime(&now);
  11. //WS2812B define
