A Logic Checker

In this chapter I’m going to explain how to build simple-to-intermediate logic checkers using an Arduino together with common electronics parts that you may have in your junk box. Also, I’ll show how the Arduino can drive a seven-segment LED display directly using a basic circuit and a sketch. I will use the design of my open source logic probe as a case study to illustrate the design process you can use to create your own electronic gadgets. In the process I’ll show you how to create truth tables to design and troubleshoot digital circuits.

A truth table is a graphical analysis tool used to explain the operation of digital ...
