Here's the perfect tool for electronics hobbyists and studentseven complete beginners--who want to understand digital logic and build their own low-cost logic circuits. You get more than 20 projects for designing, constructing, and interfacing easy-to-do TTL (Transistor-Transistor Logic) circuits. This guidebook provides everything from directions for setting up your own digital electronics lab to explanations of needed math and basic electronics. Construct your own simple 8-bit computer and learn how computers really work. Find tips for making circuits that switch, count, time, measure, control, combine input and output, switch-bounce, "think, " and much more. Get guidance on creating, prototyping, and debugging sophisticated applications of your own design. Useful tables, data and formulas, and demonstrations of project assembly techniques, such as wrapping and soldering, add to the hands-on support, along with the reusable printed circuit board included with the text.
