A virtual laboratory based on HTML5

Experiments of digital circuit are essential to this course. Traditional experiments can not meet the actual need of students, which is doing experiments anytime and anywhere. HTML5 makes the Web applications more and more flexible. In this paper, we designed and implemented a virtual laboratory base on HTML5. In this system, all the electronic components are virtualized into Javascript components which enabling users select virtual electronic components to build circuit on demand. Thus users can get results immediately by inputting data into the virtual switches. We have conducted a large number of experiments, consequently, it is convinced that students can perform experiments as required by using the system.
