void Program::run() { for (;;) { // program code here checkSerialInput(); } } The function initArduino() is inlined and handles the two initialization routines required to setup the Arduino ...

(Hint: there’s no Arduino-provided code involved; hardware registers and the __asm keyword show up.) If you learned embedded programming in an earlier era, this will probably seem glaringly obvious.

The Arduino and the Rasberry Pi often get compared when prospective tinkerers look for a device to mess around with ... is a microcomputer you can write code directly onto the device.

If you've used Arduino technology, chances are that you've come across libraries written by Adafruit's Limor 'Ladyada' Fried for the many devices and sensors that the company has to offer.
