Internet of things (IoT) has become the trend of world research and has become a necessary field of knowledge that should be taught in institutions.
This paper presents a basic laboratory module aimed at helping undergraduates understand the interfacing and connectivity technologies involved in IoT. Interfacing includes identification, embedded sensing and embedded actuating while connectivity includes low energy wireless connectivity and web services. Users will start by selecting a physical variable of interest and an action to be carried out based on the measured physical variable. The user will also have to select a connectivity option based on network types and transmission technologies for communication between a sensor or actuator and a gateway.
For this work, an Arduino Yun and a mobile device was employed to show how a laboratory module which connects to a web app and an Android mobile app can be designed for pseudo experiments that explain each step of a proposed teaching paradigm for IoT. The Arduino Yun acts as the gateway. A sensor node is created using Arduino Pro Mini with temperature and humidity sensors, and a linear slide actuator. Web app and Android app are also created for internet and mobile connectivity respectively.
At the end of performing the experiment, the student would have a clear understanding of the operation of selected sensors and actuators, analog and digital signals, characteristics of things to interface, relationships and possible ways of interfacing, data presentation and connectivity types, and basic security of signals, This work has led to a teaching paradigm which follows a list of steps that bring students to a quick understanding of IoT.
Finally, from students' performances, graphs are plotted to show the satisfaction and understanding of undergraduate students in basic IoT concepts.
