Over the last decade a complete plethora of free-open
hardware and software resources have been
developed for use in engineering and other fields
, more recently significant advances have been
achieved in the field of microcontrollers  and
data acquisition and analysis 
Virtual laboratories have become an extended tool used for teachers and students around the world in all
stages of education, ranging from elementary school to higher education. The virtualization of
laboratory practicals has shown to be an effective mean to extend learning scenarios beyond the
classroom or laboratory at campus site.
THREE WIDELY KNOWN FREE-OPEN RESOURCES THAT CAN
GET INTEGRATED INTO A VIRTUAL LABORATORY
Requirements and functional arrangement for
electronic instrumentation virtual laboratory
The main goal is to design and implement a set of practicals belonging to the Electronic
Instrumentation course for the Electronic Engineering undergraduate program.
Laboratory practicals on temperature sensing, error estimation, data acquisition, remote monitoring
and sound analysis have been designed to be integrated to course virtual activities

General overview of the Virtual Laboratory operating
Current free-open tools exhibits acceptable
performance and offer to users and administrators
enough options to design and put into operation,
implementations covering the essential needs for
Virtual laboratories and similar e-learning tools
improve and complement traditional “atclassroom” education instead of abolishing it.
The solution based in open-free resources has
flexible features that enhance time sustainability.
The less dependent design on hardware-software
elements, allows a wider spectrum of operating
variants, including the adoption of teaching
approaches or models dynamically, as time passes
according to academic results.
