Design of a Flexible Hardware Interface for Multiple Remote Electronic Practical Experiments of Virtual Laboratory

The objective of this work is to present a new design of a Flexible Hardware Interface (FHI) based on PID control techniques to use in a virtual laboratory. This flexible hardware interface allows the easy implementation of different and multiple remote electronic practical experiments for undergraduate engineering classes. This interface can be viewed as opened hardware architecture to easily develop simple or complex remote experiments in the electronic domain. The philosophy of the use of this interface can also be expanded to many other domains as optic experiments for instance. It is also demonstrated that software can be developed to enable remote measurements of electronic circuits or systems using only Web site Interface. Using standard browsers (such as Internet explorer, Firefox, Chrome or Safari), different students can have a remote access to different practical experiments at a time.
