[思路]:树莓派安装express服务器,访问服务器,与服务器交互,从而控制硬件,最终实现树莓派引脚电平控制,进而实现与树莓派电路板引脚相连的LED亮与灭。 ExpressJs: Fast, unopinionated, minimalist web framework for Node.js http://expressjs.com/ 树莓派: Raspberry Pi 4: Your tiny, dual-display, desktop comp...
接线非常简单,正极接5V(我的灯带只有1米长,用树莓派Pico供电并不吃力,如果比较长的灯带,需要额外电源),一端接地,树莓派GP15接信号线Din。灯带里面的Do不用管它,它实际上是Dout的意思,信号经过Din处理后,点亮那个灯,吃掉一些字节,再经过Dout出来,从而可以串联更多的灯。 官方文档《Raspberry Pi Pico Python SDK》...
