2024作業2-2 ESP32 + RFID + (Node-Red & SQLite ) + Line Notify

2024作業2-2 ESP32 + RFID  + (Node-Red & SQLite ) + Line Notify 



(Arduino  ,  Node-Red  程式中的 alex9ufo 全部改成自己的英文命名)






使用Node-Red 第一次一定要先建立資料庫 不然看不到資料

資料庫的目錄位置查sqlite節點

每一個sqlite節點都要修改成自己的目錄, alex9ufo MQTT Topic都要修改成自己的命名

 




arduino_secrets.h 裡面的內容

#define SECRET_SSID ""
#define SECRET_PASS ""




Arduino 程式需要 arduino_secrets.h 

// Wifi 與 MQttClient 程式庫
#include <ArduinoMqttClient.h>
#include <WiFi.h>
#include "arduino_secrets.h"

Node-Red 程式畫面



新增 RFID 卡片 UID

刪除一筆資料



刪除資料庫 與  建立資料庫


自動比對模式 (查詢模式)


手動比對模式 (查詢模式)



自動比對模式 / 手動比對模式 ==>查不到資料

Line Notify  (需改成自己的權杖 不然我會收到各位的Line)

msg.headers = {'content-type':'application/x-www-form-urlencoded','Authorization':'Bearer A4wwPNh2WqB7dlfeQyyIAwtggn1kfZSI5LkkCdia1gB'};
msg.payload = {"message":msg.payload};
return msg;

(Set Line API function內)
我的權杖A4wwPNh2WqB7dlfeQyyIAwtggn1kfZSI5LkkCdia1gB
需改成自己的權杖




Line 權杖的取得
