Universe of Instrumentation


Are you ready to learn about amazing instruments? You’ve come to the right place! We’ve broken down engineering instruments into four categories:

  • Measuring electricity: current and voltage
  • Measuring time and electricity: clocks, radio, computer signals
  • The “Electronic Eye“: seeing with electronics
  • Physical-electric sensors: how we detect sound, pressure and movement with sensors that have physical contact

Our course consists of web pages with embedded videos. You can move through the pages quickly, only getting a basic background of the technology, or you can click on outside links to pages with much more detail. Additional units will be completed in the future.


Lets begin with Unit one.

Or continue your progress with Unit II, Unit III, or Unit IV

Note: we list sources for all the pages in this unit in our Credits page.
