The ESR electronics Tricorder, Part 1
In this article I describe the beginnings of a device that I like to think of as a Tricorder for electronics. This is the first of a three part series in what will (hopefully) be the start of a series of articles that describe ways to use Arduino boards and AVR microcontrollers to build useful, low-cost test, measurement, and control devices.
For additional details and definitions be sure to check out my books “Practical Electronics: Components and Techniques” and “Arduino: A Technical Reference“. Both are available from O’Reilly, Amazon, Barnes and Noble, and numerous other places where fine books are sold.
