Development and application of internet of things educational tool based on peer to peer network

With growing interest in IoT across the Peer-to-Peer network industry, basic education programs on IoT for learners are expanding. The purpose of this study was to analyze the difficulties met by learners in basic IoT education, to design and develop hardware tool, and to evaluate the usability of these tool. In this study, the needs of teachers and learners on the tools were analyzed, and design guidelines established. The design guidelines, based on the analysis of needs, suggest the functions of hardware board, miniaturization of board, modularization of sensor parts, and usability and expandability of the tool. A hardware board is designed and developed based on the guidelines. The developed board is then used for basic education on IoT for learners, and the usability of the board is evaluated. The results showed that the new hardware tools provide higher usability than the existing Arduino board. This study is meaningful in that it provides a reference for future IoT educational tools, and that it highlights the importance of promoting learner-centered education.
