Norman Dunbar is an 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 piles of notes expanded, Norman has now decided to publish his work.
