Two reasons can be identified for the immense success of the Arduino platform. First, the cheap, ready to go processor board greatly simplifies the introduction to hardware. The second success factor is the free and open-source programming suite that does not require an installation procedure. Simple entry-level examples ensure rapid successes. Complex selection procedures for parameters like the microprocessor version or interface settings are not required. The first sample programs can be uploaded to the Arduino board, and tested, in a matter of minutes. The Arduino user is supported by an array of software libraries. However, the daily increasing volume of libraries poses initial problems to the newcomer, and the way ahead may be uncertain after a few entry-level examples. In many cases, detailed descriptions are missing, and poorly described projects tend to confuse rather than elucidate. Clear guidance and a single motto are missing, usually owing to the projects having been created by several different persons—all with different aims in mind. This book represents a different approach. All projects are presented in a systematical manner, guiding into various theme areas. In the coverage of must-know theory great attention is given to practical directions users can absorb, including essential programming techniques like A/D conversion, timers and interrupts—all contained in the hands-on projects. In this way readers of the book create running lights, a wakeup light, fully functional voltmeters, precision digital thermometers, clocks of many varieties, reaction speed meters, or mouse controlled robotic arms. While actively working on these projects the reader gets to truly comprehend and master the basics of the underlying controller technology.

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().
