基于arduino的ESP8266天氣預報設計
附錄：代碼、天氣相關圖片、字樣等素材。

單片機源程序如下:

#include<ESP8266WiFi.h>
#include<avr/pgmspace.h>
#include<SPI.h>
#include<SD.h>
#include<ArduinoJson.h>

#define exit_bt 930
#define left_bt 648
#define right_bt 393
#define enter_bt 144
#define null_bt 22 //不按按鍵時的值（由于會受外界干擾不為0）
#define City_Code_MAX 35 //城市數量(0~35)
#define MAX_CONTENT_SIZE 1000 //接受http響應內容的最大字節數
#define HTTP_TIMEOUT 5000 //最大響應時間
