Tutorial - Controlling The Real World With Computers

This site uses hands-on experiments to show the basics of how real things in the real world are controlled with computers.

Controlling The Real World With Computers

This site is also for anyone who is the least bit curious about monitoring and controlling such things as motors, lights and switches, or recording and playing everything from sound to the arm position on a robot.

Experiment 7 - Bi-directional Control Of Motors And The H-Bridge

It would be useful to be able to run a motor in either direction. That's simple with a motor of the type that's been used in the experiments thus far. Reverse the DC power connections on such a motor and its shaft will rotate in the opposite direction. One way to control direction is to use switches arranged in the following manner:

Temperature Logger

Temperature Logger

These pages describe the complete design of a temperature logger. Over 100 of these loggers have been built. 3 by the author, the rest by people that have stumbled across this site. (There may well be more: the zip download averages three a day; these pages have been up since July 1999.)

Fox Delta Amateur Radio Projects Kits

Fox Delta Amateur Radio Projects Kits

FoxTrak  -This is a tiny APRS trracker measuring 4.5cm x 7cm and supports open source firmware and more...
APRS TINY TRACKER USING PIC16F84A

Amateur radio projects that I built for myself and have PCBs & kits made available to other radio amateurs interested in building similar projects.


This PIC based LCD Temperature measurement project was planned to measure two Temperatures Simultaneously. It can be effectively used to measure your room temperature and may be used for measuring RF Amplifier Temp.

Sumo Robot project of Dave Chu

Dave's Sumo Robot project

The following is my Computer Science project Comp490 and Comp492 in progress. It is a SUMO robot for our local RoboWar tournament. I have been, for the pass two years a participant of the annual RoboWar competition. So, this year I've decided to try to get credit for doing it.

"I was fortunate enough to find a professor who was willing to supervise my project Dr.Ferhat Khendek. I have decided to do the documentation in HTML format and make it public to anyone who is interested in robotics."

There are two class of robots, remote controlled and autonomous. Remote controlled are operated by a human participant via RF link. Autonomous on the other hand has to be self contained with no human influence in its operations with the exception to its programming.
