Abstract
The courses and disciplines in the exact sciences are based on practical work (PW) which complements the theoretical teaching. Remote Labs are a recent approach used for educating experimental manipulations by using the performance of information and communication technologies. This work aims to propose the design of an IoT system allowing several remote manipulations in analog electronics. This solution is mainly based on the Red Pitaya STEMLab board, in particular for communication and remote control for measurements and data acquisition through different protocols. The low-cost system provides an intelligent selection between the different integrated practical works on a developed board, as well as other ones carried out externally as extensions according to the professor's needs. The analysis of the integrated manipulations was done taking into account the minimum latency of the remote control as well as its portability to save time, space, and money without loss of quality and quantity. The presented results relate to a PW of analog electronics, a “RC charging and discharging circuit” has been considered for a comparison of this Remote system with the same PW performed by the classical method "hands-on laboratory". Our purpose in this study is the development of a control system to maximize the available resource as well as to improve self-learning ability in the electronic field.
Highlights
In a developing country, economic, social and cultural progress can only be achieved through higher education that produces quality skills
The second step concerns the evaluation of the IoT system, a practical work-related to analog electronics have been considered for the remote laboratory experiment
In this work, we have proposed the conception and implementation of an IoT system allowing the remote realization of several analog electronics laboratories
Summary
Economic, social and cultural progress can only be achieved through higher education that produces quality skills. Hands-on sessions are an essential part of university curricula, they offer another entry into the subject, another rhythm, with a smaller group of students [5,6] These activities have proved to be essential in scientific and technical training tasks in which students manipulate real objects or materials or witness a demonstration by the teacher, in technical streams such as engineering, where students are required to complete practical exercises and assignments essential to their learning [7]. The overcrowding of higher education institutions in developing countries is one of the main problems of theoretical education, which takes precedence over practical education in a more remarkable way In this situation, it is students who deplore this situation, teachers are very dissatisfied with this overcrowding of universities. There are too many students for the same infrastructure, the same equipment, and the same teacher [8]
