boards in a few electronics shops, but people interested in electronics could
also download its schematic

and build it themselves.
Over the years, the Arduino team improved the board’s design and released
several new versions. They usually had Italian names, such as Uno, Duemi-
lanove, or Diecimila; you can find online a list of all boards ever created by
the Arduino team.

Here’s a small selection of Arduinos. They may differ in their appearance, but
they have a lot in common, and you can program them all with the same tools
and libraries.
Although they’re the same in principle, they differ in some details. The Arduino
Due
3
has many more IO pins than most of the other Arduinos and uses a
powerful 32-bit ARM core microcontroller, while the Arduino Nano
4
was
designed to be used on a breadboard, so it doesn’t have any sockets. From
my experience, beginners should start with one of the “standard” boards—that
is, with an Uno, for example.
