In this chapter, we looked at four different way of structuring a Python program that interface with electronics. We learned about an event-loop approach to programming, two variations on a thread-based approach – callbacks and a publisher-subscriber model – and finished by looking at how an AsyncIO approach to programming works.
Each of the four examples we covered was very discrete and specific in its approach. While we briefly discussed the relative benefits and pitfalls of each approach along the way, it's worth remembering that in practice, your projects will likely use a mixture of these (and potentially other) approaches, depending on the programming and interfacing goals you are trying to achieve.
In the next chapter, we will turn our attention toward IoT platforms and present a discussion of the various options and alternatives that are available for building IoT programs.
