In this chapter, we learned a little about HTTP. We came to understand how it could be used for serving up content over the Internet. Next, we studied web servers and how they can be used as the mechanism for serving this content to the browser, in order to be rendered with HTML.
Following this, we used our Python skills, developed in earlier chapters, to write a couple of web servers. The first served a simple HTML page, and the second pulled data from a SQLite database and implemented the Flask framework.
This now leads us to our final chapter on connecting to third party microcontrollers. Here we will look at how other devices such as Arduino can talk to the Raspberry Pi.
