Summary

In this chapter, we worked with Tornado web server, Python, the HTTPie command-line HTTP client, and the mraa and wiring-x86 libraries. As in the previous chapters, we took advantage of Python's object-oriented features and we generated many versions of RESTful APIs that allowed us to interact with the board in computers and devices connected to the LAN.

We could compose and send HTTP requests that printed number in LEDs, changed the brightness levels for three LEDs and generated millions of colors with an RGB LED.

Now that we created our first RESTful APIs that made is possible for computers and devices to interact with our IoT device, we can take advantage of additional features that allow us to read digital inputs and analog values, which is the topic of the next chapter.
