collaborative research. Not only is the calculation of the display appealing to children of all ages, you can also make cool things yourself.# # #附录When programming Gpio, there are two ways to point them out: GPIO encoding and real-time codingThe encoding of the GpioThe computer uses this method to recognize the GPIO pin. The exact numbers don't work for people, they jump to the place, so it's not easy to remember them. You can print a reference book

route is very simple, that is, reading the index template (the template is html) and sending it to the client (browser), because the path is "/", that is, for example, the IP address of Raspberry Pi is 192.168.0.10. Use http: // 192.168.0.10: 8080 to access our "/" route (the default port of the bottle is 8080) Similarly, the second route path is "/cmd", that is, access http: // 192.168.0.10: 8080/cmd to a
