Microcomputers are commonly interfaced to external devices in scientific, industrial, and consumer settings for data acquisition and for control. The general problem under consideration is the task of taking measurements of some continuous phenomenon, transforming them into digital form, and storing the data in the microcomputer for later use.…

The main part of this project involved using a computer, either an Apple or an IBM, as a chart recorder for the infrared (IR) and nuclear magnetic resonance (NMR) spectrophotometers. The computer "reads" these machines and displays spectra on its monitor. The graphs can then be stored for future reference and manipulation. The program to…

This project involved interfacing of microcomputers with three chemical instruments--Nuclear Magnetic Resonance (NMR), Infrared Spectroscopy (IR), and the spectrophotometer. A Pascal program called "Spectrum" allows data from the NMR to be read and graphed, a specific area of the graph zoomed, ratios of specified areas of the graph…

Provides ideas for using the same port connection of personal computers to interface with laboratory instruments. Contains specific instructions on how to build transducers. Includes plans and diagrams for thermistors and light meters as well as computer programs for displaying instrument readings on monitors. (TW)

Describes a chemistry lab experiment in which a microcomputer is used to graph data. In the experiment a catalyst is used to decompose a commercial bleach. The computer's game port is used with a potentiometer to plot the volume of oxygen gas produced versus elapsed time. Courseware information is included. (TW)

Microcomputer-based instrumentation packages enable computers to collect continuous analog data, convert data to digital form for processing, and display results on monitor. Discusses classroom advantages of these packages, describes one package for teaching harmonic motion, and provides a list of currently available packages (including vendor and…

Describes an interface designed to meet the requirements of an instrumentation teaching laboratory, particularly to develop computer-controlled digital circuitry while exploiting electrical drive properties of common transistor-transistor logic (TTL) devices, minimizing cost/number of components. Discusses decoding for Pet, switches, lights, and…

Describes a project that prepares teachers to be computer literate by writing computer programs, constructing computer modules, and then integrating the teacher generated hardware and software into science laboratory experiences. Presents goals, descriptions of interface modules, reaction of participants, and objectives. (MVL)

Discusses the use of microcomputers as a universal instrument to replace more expensive instrumentation in many traditional labs. Describes the availability of microcomputers as inexpensive educational tools which can be used successfully in labs with minimal requirements on the computer. (SK)

This guide offers information and procedures necessary to train electronics engineering technicians. Discussed first are the rationale and objectives of the curriculum. The occupational field of electronics engineering technology is described. Next, a curriculum model is set forth that contains information on the standard electronics engineering…
