Web based access and control environment for experiment on electronic circuits

Abstract

Electronic laboratory experiments mainly describe the design and implementation of various circuits which assists theoretical study. Web based environment for these experiments helps the learners with any time accessibility of the remote hardware resources through online environment. The graphical programming language LabVIEW and data acquisition facilities provide an attractive solution through the availability of rich functions to acquire and analyze the signals. The custom interface circuits are designed to configure the circuit remotely based on the design requirement. The remote switching of different components to the circuit experimentation is achieved through the transistor switching circuitry. The switching circuitry is operated by the Boolean control actuations on graphical user interface, which can be remotely operated through a common web browser. A case study is presented with the circuit experimentation on the generation of frequency modulation signal.
