1 From installing the operating system to the first Python programme
The Raspberry Pi has hit the headlines in recent months like no other electronic device in this price range.
Although it does not look like that at first glance, the Raspberry Pi is a full-fledged computer about the size of
a credit card - at a very reasonable price. Not only the hardware is cheap, but also the software: The
operating system and all applications required for everyday use can be downloaded free of charge.

The Raspberry Pi with its specially adapted Linux system with graphical user interface is a power-efficient
and silent computer replacement. Its freely programmable GPIO interface makes the Raspberry Pi
particularly interesting for hardware tinkers and the maker scene.

The Raspberry Pi is a full-fledged computer despite its tiny size. Like with any "normal" computer you still
need some accessories in order to use it – an operating system, power supply, network, monitor, keyboard
and various connecting cables.
