Norman Dunbar is a retired Oracle database administrator. Norman has had a long-running relationship with electronics since childhood and computers since the late 1970s, and the Arduino was a perfect marriage of the two interests.

With a love of learning new things, examining and explaining the Arduino Language and the hardware became a bit of a hobby, and as his piles of notes expanded, Apress decided to publish his work as Arduino Software Internals back in April 2020 with a second edition in 2024.

Once more his notes became a book and Arduino Interrupts was published by Apress/Springer in December 2023. Because he never remembers exactly how much work, and how hard it is to write a technical book, Norman has now completed writing the third book in the Arduino Trilogy, and you are reading it now! Norman’s motto continues to be don’t think, find out.
