Abstract: During the pandemic spread of COVID-19, it is very essential to develop modern and technology-based
alternatives for traditional education. Virtual laboratories promote education and will be used in the future as the primary
instructional instruments. Learning in a virtual laboratory minimizes teachers' worries about time, expenses, or hazards
involving choosing improper, ineffective, or possibly harmful experimental approaches and fulfills the urgent need for social
distancing to avoid the spread of infectious diseases. It offers higher student-to-component interaction and perception.
Learning in a virtual lab enables more data to be obtained. The purpose of this research study is to train the student for
practical application and experiment with measuring tools such as voltmeters and data acquisition systems. The student can
also compare two outputs: the first is the outcome of the actual scheme, and the second is the virtual signal, the pure sine
wave that can be regulated by frequency, amplitude, and phase. It can also send and obtain information from the teacher to
the student. The teacher can see and follow up on what the learners are doing, so the teacher can better regulate the
classroom. Experimental results show the superiority and the success of our proposed method in enhancing students’
learning experience.

1- INTRODUCTION
There is a prevalent issue nowadays that learners of science and engineering lack the professional
understanding and abilities of communication between parts and devices. Students cannot exercise and
obtain data with the theory and research methods. Among some technical colleges, these issues are
becoming more prominent. [1]
The e-learning environment is seen as a significant resource for helping ancient traditional
formats of learning and transforming the nature of education. We will design the virtual lab in this
research using the "Lab View" program to provide learners with a distinctive manner of providing the e-
learning environment with higher interaction between them and the element. [2]
Laboratory environment relates to the laboratory that colleges and educational organizations are
building for student teaching. The classroom lab is a significant component of the setting of teaching and
learning. It provides students with a useful, safe, and intuitive place to do scientific experiments. The
experiment can stimulate interest in learning, experience the fun of exploration, enhance the current
knowledge framework, and enhance operational, diagnostic, analytical, design, and innovation
capabilities. [3]
E-learning is one of the most significant learning techniques in the future, so many studies are
showing the significance of e-learning and the most significant studies in this sector or implementation
are: Abdullah-Alhabeeba et al [19] also addressed the notion of e-learning, explaining the mechanisms of
e-learning and explaining the distinction between traditional techniques of learning and e-learning.
The current health and safety constraints imposed because of the widespread of COVID-19
pandemic and the fear from the second wave of infections and fatalities necessitates the development of
remote learning tools to allow for social distancing and avoidance of direct contacts between teachers and
learners and between learners and other learners.

M. Travassos Valdez et al [4] addressed one of the key educational instruments in the future, i.e.
3D Virtual Labs, and designed a plan for Electrical Engineering lessons that aim to train learners to meet
competitive difficulties.
Fuan Wen et al [20] addressed the notion of Experimental Enhanced Educational Environment
(4E) and clarified the benefit of the 4E, which brings together the theoretical survey, experimental
operation, cooperation, communication, and social exercise as the person who is the subject of the
research. It also enables education to open a true application at a reduced price and enables learners to
adapt more efficiently to future development.
The contribution of this research is in these studies that focused on and discussed safe learning at
lower-cost technical schools and the use of professional software programs like "LabVIEW," "Team
Viewer" and "Circuit Wizard" for two purposes in these studies: the first is safety learning in the electronic
laboratory and the second is to train the student for practical implementation. Figure 1 indicates the front
panel of our proposed system.
Figure 1. The front panel of our proposed system
So helpful and simple is the "LabVIEW" programming, so it is used in the project. It includes many
items such as terminals, constants, structures, features, and sub-VIS (sub-virtual instruments). "LabVIEW
"enables users to design their apps by dragging and dropping these items onto a diagram and linking them
through cables. All terminals in the block diagram are shown in the front panel window (the virtual
instrument's graphical user interface) which acts as input or output of information. "LabVIEW" utilizes
different protocols like TCP/IP, socket data, etc. To transfer data between student and teacher, it will use
the Ethernet module with the TCP/IP protocol. The team viewer software will also be used to transfer data
and signals between the computer of the student and the computer of the teacher. [7]
The sampling speed of the oscilloscope is limited by the baud rate of the UART. The Arduino
sketch is coded to read the ADC using ISR, and the UART baud rate is configured at 9600, which sends
data at 80µs intervals. This gives an effective sampling rate of 10kSa/s.
