重启Arduino IDE,打开文件->Sketchbook->Library->Adafruit_NeoPixel->strandtest sketch。 在arduino应用开发中,对于WS2812等全彩LED灯带控制,这里我们采用Adafruit NeoPixel Library来实现(主要是因为目前我只知道这个库,其他库暂时还没有去深入了解,好尴尬 -_-```)。 在使Adafruit ...

比如你玩pid ,你不懂pid 可以直接Arduino IDE的库管理中下载别人封装好的PID库,比如你想玩个MQTT远程控制,Json解析/正则表达式,NTP服务 ... 不需关心MQTT的底层原理,Json怎么解析。虽然传统单片机上也可以移植cJSON库进行解析,但是ArduinoJSON可以使用更优雅的方式解析json。
