A&D Board User Manual and Test Procedure

General Operating Instructions

1) Read this manual in its entirety before engaging in any experimentation.

2) The A&D (ANDY) board should be tested upon receipt to assure that all sections of the

board operate within specifications. See the Test Procedure section.

3) Never construct a circuit or insert any wiring with power applied to the board.

4) Construct the circuit per your laboratory manual and then double check the wiring.

5) Should a problem occur, unplug the power cord from the board immediately and look for

obvious errors.

6) If you have a disaster, follow the instructions for technical support, which should be in your

syllabus or course web site.

Description

The objective of the ANDY board is to provide the student with an easy to use, mobile,

and multipurpose learning tool that can be used to develop many aspects of circuit design and

analysis. The ANDY board is designed to support a rich, hands-on experience in digital logic,

DC circuit analysis, and AC circuit analysis through the use of take home labs and design

projects. The board provides plenty of breadboard space for students who may need to do more

than one lab concurrently for different courses. Because of its small size and power supply, the

board is mobile, providing the student with the opportunity to work on experiments wherever she

or he feels comfortable. The ANDY board provides a more relaxed environment to learn

material, which leads to better comprehension.
