The Raspberry Pi is an exciting technology, not only because of its small size, low cost, and low resource usage, but because it makes connecting the world of programming to real-world circuitry simple and accessible in a way that nothing had before. In this chapter, you learned how to configure the Raspberry Pi to run PyQt applications. You also learned how to control circuits using PyQt and Python, and how circuits could control actions in your software.
In the next chapter, we're going to bring the World Wide Web into our PyQt applications using QtWebEngineWidgets, a full Chromium-based browser inside a Qt Widget. We'll build a functional browser, and we'll learn about the ins and outs of the web engine library.
