Welcome
WELCOME TO
THE OFFICIAL
PI MAGAZINE!
After decades of it being the most
popular operating system in the
home, it’s been interesting to see Microsoft
experimenting with expanding the uses of
Windows. Recently, the firm got behind the
maker movement, which led to Windows 10
being ported to the Raspberry Pi last year, in
the form of Windows 10 IoT Core. There’s been
a great reaction from the maker community,
and it’s currently included on NOOBS for
everyone to use.
Now with the Raspberry Pi 3 out, Windows
10 IoT Core has much more power to play with
and the team at Microsoft are keen to show
off what it can do. They’ve even made a new
kit full of great project parts so you can make
the most out of Windows 10 on Raspberry Pi.
To celebrate this, we’ve got a whole feature on
Windows 10 IoT Core – starting on page 14 –
that shows you what’s in the new kit, some of
the amazing things you can do with IoT Core
on Raspberry Pi, and some quick lessons to get
started making with Windows.
We hope you enjoy the issue!
W
indows is synonymous with computers.
