如何用ESP8266做一个天气预报，趣味与功能并存

vijah

1、硬件 用一个四博智联提供的nodemcu。一个OLED屏，一个USB线，4根杜邦线，可以上网的路由器，电脑。      3V3---VCC      GND---GND      GPIO4(D2)---SDA      GPIO5(D1)---SCL 2、设置路由器 把路由器账号设置为把路由器账号设置为 账号：xh003 密码：zxd+19901120= 3、烧录程序 打开ESP_TOOLS下载工具，选择8266. 工具下载：http://bbs.doit.am/forum.php?mod ... 6&highlight=TOO 点击START.等待烧录完成。 烧录完成后复位一下nodemcu。等待10s左右。 测试结果如下： Arduino代码如下： #include <ESP8266WiFi.h> #include <ArduinoJson.h> #include <Wire.h> #include "OLED.h" static const char logo[] PROGMEM={ 0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0xff,0x7f,
