Editorial Reviews Review "An important addition to the technical library of any engineer, technician, student, or electronics hobbyist who works with PCs." --TIES Magazine "According to his publisher, Paul Bergsman has taught technology and mathematics in the Philadelphia public schools for 21 years. The clarity and thoroughness displayed in this book suggest to me that he's a pretty good teacher. I'm giving his book an A+." --Electronics Handbook Review "An important addition to the technical library of any engineer, technician, student, or electronics hobbyist who works with PCs." --TIES Magazine "According to his publisher, Paul Bergsman has taught technology and mathematics in the Philadelphia public schools for 21 years.

Book Description Connect your MS-DOS/Windows PC to the real world with this bestselling book! Control stepper motors, turn appliances on and off, monitor fluid levels, control a home security system, convert thermometer readings to digital values, detect magnetic fields, and do other useful stuff with the circuits and software found in this book. All circuits connect directly to the parallel printer port of your PCyou don't have to modify your PC in any way. Each circuit is complete with a schematic, description of circuit theory and operation, a parts list, construction and usage tips, and full source code in C, Basic, and Pascal for the controlling software. You can use each circuit "as is" or modify it for your particular needs. Do as thousands and thousands of others around the world have doneadd this book to your electronics reference library! Over 200 large-format pages plus HD floppy disk. -controlling stepper and servo motors -generating audio tones and speech -converting input voltages to binary values Book Info Sourcebook for ideas on how to control and monitor real world devices with your IBM/IBM compatible computer. Most ot the circuits presented connect to the parallel printer port. Paper. 3.5 inch disk included.
A good book for the right match: This book goes straight in to code, no connections or words about interface. Although he has lots of projects and lots of code, including a disk, unless you know how to use cable connections from board to PC or PC to whatever you are trying to control (he has a motor project) then you will be wasting your time with it. If you are adventurous or know how to connect, then the book is generally pretty good. Has 40 projects which vary quite a bit and the circuit schematics for some projects also. But definitely not for a beginner.
Reviews:
I wish I had a copy 15 years ago... -- Paul's book was not written for those lacking experience in the areas of both electronics and programming. This book ties those fields together very nicely. I really wish I had a copy of this book earlier in my life as it is truly a goldmine of information. The code in this book is for MS DOS, *NOT* MS Windows. Windows handles the parallel port kinda funny and this code is for direct access (which Windows doesn't like). This means you can't run the code in a DOS window. I've adapted some of Paul's code for use on Linux (minimal rewriting) and for control of many laboratory instruments and data logging gear.
Very good book If you do want to controll devices with your computer, this book is what you need. Because of this book I learned a new computer language (Pascal). I have built the circuit on page 238, and it works great, and now I can see how my programs work. I highly recommend it.
Bad Book -- This book is bad. It is poorly written and the programs did not work on my computer. Even the first project--intended as a simple confidence-builder--required that the code be completely rewritten. Deciphering the author's programming was maddening. Also, some of the projects are dumb: is anyone *really* going to build a burglar detector from this book?
A valuable resource with real world examples of interfacing -- Controlling the World With Your Pc covers a vast array of interface topics, from stepper motors to alarm systems to Analog interface. The text is clear and straitforward with useful discussion of the circut and the accompanying program. The programs are well documented so only a rudimentary knowledge is necessary to get through the examples, and some programming tecniques can be learned just form the examples. The book gives enough information to facilitate further developement of custom interfaces based on those in the book, or those that are completely origional
