An 8-in-1 test & measurement instrument for the electronics workbench A well-equipped electronics lab is crammed with power supplies, measuring devices, test equipment and signal generators. Wouldn‘t it be better to have one compact device for almost all tasks? Based on the Arduino, a PC interface is to be developed that’s as versatile as possible for measurement and control. It simply hangs on a USB cable and – depending on the software – forms the measuring head of a digital voltmeter or PC oscilloscope, a signal generator, an adjustable voltage source, a frequency counter, an ohmmeter, a capacitance meter, a characteristic curve recorder, and much more. The circuits and methods collected here are not only relevant for exactly these tasks in the "MSR" electronics lab, but many details can also be used within completely different contexts. Errata/Updates In the programs printed, all instances of “be()” should read: sei().

This book is intended as a highly-practical guide for Hobbyists, Engineers and Scientists wishing to build measurement and control systems to be controlled by a local or remote Personal Computer running the Linux operating system. Both hardware and software aspects of designing typical embedded systems are covered in detail with schematics, code listings and full descriptions. Numerous examples have been designed to show clearly how straightforward it can be to create the interfaces between digital and analog electronics, with programming techniques for creating control software for both local and remote systems. Hardware developers will appreciate the variety of circuits, including a novel, low cost modulated wireless link and will discover how using Matlab® overcomes the need for specialist programming skills. Software developers will appreciate how a better understanding of circuits plus the freedom offered by Linux to directly control at the register level enables them to optimize related programs. There is no need to buy special equipment or expensive software tools in order to create embedded projects covered in this book. You can build such quality systems quickly using popular low-cost electronic components and free distributed or low-cost software tools. Some knowledge of basic electronics plus the very basics of C programming only is required. Many projects in this book are developed using Matlab® being a very popular worldwide computational tool for research in engineering and science. The book provides a detailed description of how to combine the power of Matlab® with practical electronics.
