This is the third manual for the Raspberry Pi that I have bought and is by far the best. It is bigger, 412 pages, packed with all the details a novice needs to get started but goes on much farther than the others in providing detailed hardware and software projects to a high level. It is also very competitively priced.
The writing is very clear and easy to follow with plenty of details, tables, tips, illustrations and screen shots. It explains how to keep your RPi computer up to date, download and install a wide range of free software for tasks such as word-processing, spreadsheets, photo editing, building a website and playing video/audio. The sections on programming include introductions to Linux, Scratch, Python and Pygame. The associated website provides access to allow the downloading of the programs for many of the projects.
Where this book really scores with me is the last third, written by 'Grumpy' Mile Cook, well known in Arduino and RPi forums for his hardware projects stretching back to the early days of the BBC micro. Mike has lost none of his enthusiasm for building electronic add-ons for the computer to control. The projects are very well explained, with easy to follow instructions on obtaining parts and building the hardware. The necessary software to complete the project is fully explained in easy to understand instructions. He also explains how to add analogue to digital converters and how to use them. This section includes instructions on installing SMBus for I2C, which would have been very useful to me a couple of months ago.
The trouble shooting section and excellent index allows the user to quickly find answers to problems.
Of my three RPi manuals this is the easiest to use, covers the most topics and is the cheapest. If you need a Pi manual - get this one.
