Professor Lawrence Kunle Kehinde, a former Engineering Dean and University Deputy Vice Chancellor, received his B.Sc 1st class Hons in Electronics (1971), and a D.Phil, Control Engineering (1975), at the University of Sussex UK. He had his Post Doctoral Studies in Nuclear Instrumentation at University of California, Berkeley USA (1977-1978) as an IAEA Fellow. He has spent most of his years as a Professor of Instrumentation Engineering at the Obafemi Awolowo University (OAU), Ile-Ife, Nigeria. He was the Rector of the first private Polytechnic in Nigeria. He recently concluded a 3-year Visiting Professor term at the Texas Southern University, Houston Texas USA. He has worked in Techno-Managerial position as the Director of ICT at OAU for years. His major field is Instrumentation Designs and has designed equipment, two of which had received British patents in the past. He was the founding Principal Investigator of the University’s iLab research and he currently designs remote and virtual experiments for remote experimentation. He is a Chartered Engineer, a Fellow of the Computer Professional Nigeria and a member of IEEE and ASEE.

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.

Keywords: sensor, actuator, connectivity, interface, Internet of Things, security.
