About the Author

Daniel Bates is a computer science researcher at the University of Cambridge. His day job involves inventing designs for future mobile phone processors and when he gets home, he likes playing games or working on one of his coding projects (or both!). Daniel has been a volunteer for the Raspberry Pi Foundation since 2011 and is enthusiastic about introducing new people to computing. He has previously written Instant Minecraft: Pi Edition Coding How-to and Raspberry Pi Projects for Kids (First Edition), both published by Packt Publishing.

About the Reviewers

Ed Baker graduated with a BSc in physics from Imperial College, London, in 2007 and somehow ended up working in the Entomology Department of the Natural History Museum shortly after. His work focuses on how technology, both hardware and software, can improve the way research is performed, from field data collection to final publication. Outside the technology world, he is a specialist on stick insects, cockroaches, and grasshoppers.

Recently, his work has focused on automated acoustic and environmental monitoring, protocols for sensor networks, and starting the biodiversity technology company http://www.infocology.co.uk.

Ed's first book, provisionally titled Arduino for Biologists, will be published in 2015 with Pelagic Publishing.

I would like to thank Philippa for believing that the writing and 'tinkering' would bring reward in the end.

Colin Deady's career in IT started in the late 1990s, when he discovered software testing ("they want me to break it?"), having previously fallen in love with computers when his parents brought him and his brother a ZX81 and ZX Spectrum+ in the 1980s and later an Amiga 1200 in the early 1990s. With over 15 years of experience in testing, he works as a Technical Test Manager, em...
