The Internet of Things (IoT) has become a transformative technology with great potential in various sectors, including home automation, industrial control, environmental monitoring, agriculture, wearables, health monitoring, and others. The growing presence of IoT devices stimulates schools and academic institutions to integrate IoT into the educational process, since IoT skills are in demand in the labor market. This paper presents educational IoT tools and technologies that simplify the design, implementation, and testing of IoT applications. The article presents the introductory IoT course that students perform initially and then presents some of the projects that they develop and implement on their own later in the project.

“…Remote field-programmable gate array laboratory for signal acquisition and … (Rithea Sum) 2345 boards remotely anytime and anywhere with internet access. Remote FPGA laboratories alleviate the drawbacks of traditional laboratories, such as limited accessibility, high operating costs, stringent time constraints [10], and forced closures during pandemics [11]- [13]. Given their advantages, remote FPGA laboratories have gained popularity, and can complement or replace traditional laboratories [14].…”

A remote laboratory utilizing field-programmable gate array (FPGA) technologies enhances students’ learning experience anywhere and anytime in embedded system design. Existing remote laboratories prioritize hardware access and visual feedback for observing board behavior after programming, neglecting comprehensive debugging tools to resolve errors that require internal signal acquisition. This paper proposes a novel remote embedded-system design approach targeting FPGA technologies that are fully interactive via a web-based platform. Our solution provides FPGA board access and debugging capabilities beyond the visual feedback provided by existing remote laboratories. We implemented a lab module that allows users to seamlessly incorporate into their FPGA design. The module minimizes hardware resource utilization while enabling the acquisition of a large number of data samples from the signal during the experiments by adaptively compressing the signal prior to data transmission. The results demonstrate an average compression ratio of 2.90 across three benchmark signals, indicating efficient signal acquisition and effective debugging and analysis. This method allows users to acquire more data samples than conventional methods. The proposed lab allows students to remotely test and debug their designs, bridging the gap between theory and practice in embedded system design.

“…By maximizing resource sharing, removing the requirement for physical presence, and encouraging self‐learning, a remote lab lowers the cost of conducting research. Common features for remote labs are collaboration, video streaming to keep an eye on the actual equipment, and scheduling to avoid conflicts as mentioned in Valencia de Almeida [20]. The core laboratory courses require heavy machines and controllers to do the experiments.…”

The purpose of this study is to demonstrate a novel remote lab development for improving student psychomotor skills in the Industry 4.0 course. In this work, the vision and Internet of Things‐based lab setup for third‐year undergraduates is proposed as Industrial Automation Remote Lab (IARL). The major motivation of this novel approach is to replicate Industry 4.0 in the laboratory for learning purposes to undergraduate students during pandemic condition. In industries, it is essential to collect all the data from the machines to make optimal use of resources and increase the efficiency of the system. The stored data are interfaced through the user datagram protocol to control the speed of the hydraulic actuator. In the proposed experimental work, a vision sensor‐based anydesk remote control software technique is employed to conduct programmable logic circuit (PLC) experiments. To collect the various output image data sets, numerous PLC experiments were conducted. The collection of images is classified to investigate the student performance using deep learning algorithms like YOLOv4, VGG, and YOLOv5. Based on the simulation and validation results, the IARL‐based approach with YOLOv5 outperforms the other two algorithms with 98% accuracy. Additionally, the validated statistical internal and external results show that the remote laboratory Conceive, Design, Implement, and Operate (CDIO) batch performance is highly improved over virtual laboratory CDIO batch students.
