Technical requirements
In this chapter, we will dive into some external hardware. I will show you how to talk to an Arduino microcontroller through a serial connection.
If you do not have access to such a device, do not worry. I will also talk about how to mock these devices so that you can test your code before deploying it on an actual device. You can follow along and try out the code if you encounter these devices later.
As always, you can download the source code for these samples from the GitHub repository at https://github.com/PacktPublishing/Systems-Programming-with-C-Sharp-and-.NET/tree/main/SystemsProgrammingWithCSharpAndNet/Chapter09.
