I finally published my first Arduino book which shows how to bypass the performance hampering and feature blocking Arduino library and instead access the microcontroller features directly. The book primarily for Arduino Uno, Nano, and Mega boards. The book assumes some familiarity with the Arduino (one needs to know how to write and run simple “sketches”), and some C or C++ programming skills.
I’m selling this book either printed or Kindle ebook on Amazon here or on your nearest Amazon site if you are not in the US. In the US the price is $19.99 for the Kindle version and $24.99 for the printed version.
