In this chapter, we talked about serial communication. This is a very common mode of communication both inside and between electronic devices. This chapter is also a nice introduction to other communication protocol in general, and I'm sure that you are now ready to understand more advanced features.
In the next chapter, we'll use some of the different types of serial protocol that were introduced here. In particular, we are going to talk about Arduino outputs; this means that not only will we be able to add feedback and reactions to our Arduino boards, considering behavior pattern designs such as stimulus and response for deterministic ways, but we will also see more chaotic behaviors such as those including constrained chance, for instance.
