Raspberry Pi is an ultra-small, affordable computer, costs less than most video games, but can be used to learn to code, build robots, and create all kinds of weird and wonderful projects.
The Raspberry Pi is capable of doing all the things you'd expect from a computer. However, it can be a little hard to jump headfirst into the Pi subculture, since it requires such extensive background knowledge in hardware and software development.
This book aims to get you up to speed on everything and help you to understand from the very start all that you need to do to become adept with the Raspberry Pi. We're going to be covering various topics such as:

What the Raspberry Pi is

How to set the Raspberry Pi up

An introduction to Linux

An extremely thorough introduction to programming in Python on the Raspberry Pi

Different projects that you can do with the Raspberry Pi

And so much, much more.
