Most Arduinians. . . err Arduinoers . . . ok – ‘Arduino fans’ may have already seen this, but for those who haven’t: The Arduino Programming Notebook by Brain W. Evans is a straightforward rundown of the basic code used with the ever-popular open-source platform. It’s similar to what can be found on the Arduino.cc reference library, but it comes in a handy PDF format and can even be purchased as a hard copy for a mere $5.33 USD.
