System Design of Virtual Microcontroller Laboratory Based on the Over The Air Programming

Practicum has become a crucial part of engineering education, but also in the allied subject ones. Due to developments in electronics, microcontroller-based devices are found in all aspects of everyday life. To resolve this problem, it is necessary to design a microcontroller trainer kit with a remote control system and interactive interface as a learning tool. Furthermore, the system uses the concept of a virtual lab with a remotely triggered lab type on a web platform. The technique which is used as a technique to download or overwrite the microcontroller program is the over the air programming (OTA) technique. Moreover, users are intended to perform the microcontroller practicum, controlling the I/O available on the trainer kit. OTA programming testing on microcontroller devices was successfully conducted consecutively with five experiments with different program documents. In addition, live streaming delay testing was successfully carried out with an average delay of 3.6 seconds. Finally, the result of the system interface testing from questionnaires showed that respondents rated 87% regarding the overall quality of the interface.
