WHY A DESIGN PROJECT?

Circuit design can be frustrating while trying to answer critical questions: what accuracy is needed? which circuit is best? how will customers use it? A design project provides a journey from customer need to application. This series can help propel your skill development with hands-on experiences through the 5 key design phases

  1. Define It – answer the WHY, WHAT and HOW of a design.
  2. Design It – create the specific real-world details.
  3. Build It – make something according to our design.
  4. Test It – verify it works as designed.
  5. Apply It – validate and enjoy the benefits.

WHY A VOLTMETER?

In addition to being an indespensible tool, a voltmeter

  1. showcases many key aspects of EE circuit design, even a basic design such as this one.
  2. provides real-world benefits in everday life - testing batteries (9V, 1.5V AA, etc).
  3. extends to other applications:  industrial, consumer, DIY / maker / hobby spaces, laboratory experiments.
