Question

How many architectures does the Arduino subfolder in the Hardware section contain?

(a) 2

(b) 3

(c) 4

(d) 9

I got this question in an interview for internship.

My doubt is from Compilation topic in section Arduino Programming of Arduino

Answer 1

The correct choice is (a) 2

For explanation I would say: The Arduino subfolder of the Hardware section contains support for 2 architectures; AVR and SAM. The AVR Microcontrollers are included in the most common Arduino Boards like the Uno, Nano, Mega, etc. However, some Arduino Boards like the Arduino Due don’t use AVR but use the SAM 32-bit ARM processors.
