摘要:AbstractCom port is the interface of choice for most of the projects that require communication between a computer and external device or peripherals. This study has developed an experimental tool that serves as a practical hands-on learning kit for novices in exploring and mastering hardware-software interfacing in visual environment. After exploring the developed experimental tools, learners could understand the use of computer to configure, control and connect external devices via com port in visual environment. Based on the questionnaire feedback, the developed tool seems very useful and helpful for beginners, which have minimum skills in electrical and electronic engineering in understanding hardware-software interfacing programming better.
