Böcker av Steven. Hodder

This book introduces you to remote sensing and control projects using the Arduino Uno and the 433 MHz transmitter/receiver (Tx / Rx) modules. We have been quite specific in our coverage in an attempt to thoroughly explore the subject with particular reference to a pair of readily available and inexpensive remote control modules. These modules have a good transmission range and are simple to use - particularly with the library that we have created to simplify the sending and receiving of data.Assumed Level of Previous Knowledge While this book is intended to be an informative source for a broad range of experimenters, it has been written with a narrow focus on a particular topic (remote sensing and control) using a particular resource (the 433 MHz modules). We expect that the reader will have conducted at least a few basic Arduino experiments and will have gained some familiarity with the programming language. We provide program notes for most experiments where we attempt to outline the purpose and working of the code. While we don't explain the program code in every detail, the programs are internally documented to indicate the purpose of relevant lines of code.Why We Have Created this Book and How it Teaches YouThere were two main thoughts behind this book: to investigate various remote control projects, and to do this with reference to a specific component through a series of related projects each involving a short set of experiments in which the user could gradually build up their knowledge and that additional programming code could be introduced in a readily understandable way. We wanted the reader to feel that having completed the book, they would be confident in setting up any project using these modules.

This book has been written for bright young people who want some extra material to add to their mathematical skills and to introduce some further topics of interest. It presents a range of topics in a friendly and informative way with examples and questions throughout, along with further questions and answers for each chapter. The mathematical content, along with the other topics, has been selected for intriguing aspects that are likely to appeal to students of all ages and will hopefully inspire them to seek further knowledge.The author, Steven Hodder, studied mathematics at both undergraduate and postgraduate levels and subsequently became a Senior Lecturer in Computer Science at Coventry University. He has extensive teaching experience in both mathematics and computer science - this book brings out some of the aspects that he found people enjoyed and is pitched at a level that is comprehensible to a wide range of ages and abilities.The book is meant to be fun and an incentive to find out more. There are easy bits as well as some more challenging content, but it will provide a great resource that can be referred to for many years. Apart from the mathematical content, there are also sections that include codes, philosophy, paradoxes, logic, computers, and navigation. The book finishes with a chapter on mathematical tricks which demonstrates various shortcuts and ways of impressing friends.
