Virtual Learning Object Based on a Virtual Laboratory for Microcontroller Practices

Abstract

The Virtual Learning Objects (OVA) have generated positive changes in teaching, availability and accessibility to knowledge, with the purpose of offering more flexible and multiple consultation mechanisms to consolidate a broader content of knowledge. The OVAs are digital tools that are used in virtual education, but they do not exist for specific subjects in the area of electronics, so it has been seen the need to create a virtual laboratory for teaching of microcontrollers, through a web service and the use of Google’s Fire-base database. The virtual laboratory will run on as a tool for teacher and as information and access mechanisms for the development of practices for students. Through the web application, the students will have access to the information of the practices and when connecting an Arduino card remotely, it will be linked to the database, thus achieving two-way communication, with the virtual laboratory the teacher will be able to demonstrate the operation of microcontroller practices, in real time. For the development of the virtual laboratory, a mixed methodology based on AODDEI (Analysis, Obtaining, Design, Development, Evaluation, Implementation) and component-based software engineering was used. As a result of the evidence of the operation of the virtual laboratory, a practice with 28 students connected at the same time was carried out.
