Tobias Theel

Tobias Theel works as the Technical Lead and DevOps for a German FinTech startup fino and since 2020 he has also started working for RegTech startup, ClariLab, as Lead Software Engineer. Being a software architect and an expert for Go and TinyGo alongside C# and Java, he is also iSAQB certified. Theel is a highly enthusiastic community contributor and is among the top 10% responders in C# and Unity3D as well as top 20% responders in .NET, Go, and Visual Studio on StackOverflow. When not programming for fino or ClariLab, he can be found developing games, mainly at game jams such as the Ludum Dare Jam, where he develops games from scratch within 72 hours. As an active speaker at tech talks and a participant for numerous hackathons, Theel loves to share his knowledge of software development with fellow enthusiasts.

The Arduino UNO

The Arduino UNO is one of the most popular boards out there. It is powered by an 8-bit ATmega328P microcontroller, and as of the writing of this book, there are lots of derivates from the original Arduino UNO boards. Let's get to know it better in the following subsections.

Getting to know the technical specifications

As you can see in the following table, the ATmega328P has only 16 MHz and 32 KB Flash memory. Standard Go produces a Hello World program of about 1.2 MB, which would not even fit on this microcontroller. So, we are working with very limited hardware here, but you will see that this is sufficient to build amazing projects.

Here is a brief look at the technical specs of the Arduino UNO:

Table 1.1 – Technical specifications

Note

Consider the DC current per I/O pin of 20 mA as an upper limit. You should not exceed this limit to prevent damaging your microcontroller.

Let's have a look at the pinout next...
