Raspberry Pi Computing: Analog Measurement aims to provide a full description of the process of setting up a Raspberry Pi computer to measure and record analog values using different sensors and an A to D converter. We’ll look at different versions of the Pi, along with loading and configuring the software required with some basic Linux use.

If you’ve heard about the Raspberry Pi you may know that it provides a fantastic method to learn about using a computer and to develop some skills that go beyond the basics.

What sort of things will we learn?

What sort of versions of the Raspberry Pi are there?
What hardware do I need to get it up and going?
What sort of operating system do I need and how do we install it.
How do I do [Insert any number of cool things]?
Is this book for you?

It’s not written for experts. It’s put together as a guide to get you started if you’re unsure about how to make the first move with a Raspberry Pi.

I hope you get something out of the book. Please excuse the sometimes light-hearted conversational manner in which I approach the topic and enjoy the Raspberry Pi!
