In our previous tutorial we built a web server but the code halted the processor while it waited for the next HTTP request.

In this tutorial I'll show you how to use asynchronous coding with the Asyncio package and dual core processing to build a non blocking web server that will run the HTTP protocol in the background while your microcontroller gets on with its tasks in the foreground.

The asyncio code will work for any microcontroller. The multi core code will need a Raspberry Pi Pico or ESP32 or another board with multiple cores.
