In the world of manufacturing, apart from computer systems, a new concept i.e. computer automation has arisen. This concept was originally conceived when computers started to automate things, based on the interaction with the outside world. The significant increase in the trend of automation has introduced Arduino. Having said that, Arduino is a platform that uses different inputs e.g. electronic sensors, lights, motors and other assorted gadgets, to get information from the real world and to make decisions based on that information. What Arduino builds is essentially a robot. Everyone that is interested in creating interactive environments, has the potential of doing so by using this revolutionary device. This book consists of some Arduino projects that are proposed from students of the Department of Computing, University of Northampton, in the previous years. The aim of this book is to provide students with an insight of the projects that can be developed by using the Arduino platform and motivate them for further developments in the field.
