AN INTRODUCTION TO THE EIGHT

PROJECTS

The Web Site

Use the suppon Web site. It is an important paft of all the information you have access
Lo with this tutorial. Specific to the following chapters, it has exrensive pictures on it
that show how all the projects were built by me, and these canbe a tremendous help to
you in building your own projects, even if you decide ro moalify and extend the proj
ects beyond the minimal and basic construction I have undertaken. Thc pictures are in
color and color adds a lot of uscful information.

t Techni

You must becorne comfortable with eight basic techniques to be able to design and build
instruments and conrollers tbat can monitor or conrrol the variables and prcperties you
have an inGrest in. They are

t. CouDting synchronous and asynchronous pulses.
2. Creating accurate short and long-timed intervals with rimers.
3. Using counters effectively.
4. Sensing and reading analog voltages.
5, Using pulses to control exremal devices.
6. Creating sinple scanning routines to monitor phenomena.
7. Conholling the propety or function you are interesred in.
8. Logging data over an extended time period automatically.

The eight basic consrructions in rhis tutorial cover these techniques one at a rjme. The
projects are designed ro give you an expansive view of the many possibilities that usirg
