Arduino关于天气和闹钟的问题和日期在OLED上打印的问题
在韩留学生一枚,每天在论坛搜索关于这方面的技术问题,无奈底子不是很扎实,都是靠自学,老师布置的作业也没有教很多,就让我们自己摸索,基本的功能我差不多都做了,要加一些没学过的 老师给了个json的网站好像是可以换算天气代码的那种,然后让我们添加一下天气和日期,还有闹钟,我之前想用strcmp函数实现闹钟,因为我们闹钟并不要求响,就是比如到7点了我插在面包板上的灯会亮这种,但是好像不行,如果行的话还请大神指点迷津,希望哪位贵人能帮帮小弟,每天盲人走路很是难受 小弟QQ:809886541
用的设备是 Wemos D1 和DHT11 还有OLED12864
附上代码片
