About the Author

Dr Andrew Robinson (Manchester, UK) worked at the University of Manchester School of Computer Science, where they have just launched the Great British Raspberry Pi Bake Off, a competition to get people making projects with the Pi. Andrew has quickly become a leading expert on the Pi and its astounding capabilities, including guest posts on raspberrypi.org, the official mouthpiece of Raspberry Pi. He is the creator of PiFace, which makes interfacing with the Raspberry Pi significantly easier. He is currently utilizing the Raspberry Pi as part of the team behind the BBC's Springwatch.

Mike Cook is is the co-author of Raspberry Pi For Dummies. Mike is a veteran tech author and a freelance consultant for all things to do with Physical Computing. A former Lecturer in Physics at Manchester Metropolitan University, he has written more than three hundred computing and electronics articles for the pages of computer magazines since the 1980s. Mike patrols the forums as Grumpy Mike, though he is anything but!
