When Math Powers Circuits: Exploring Inverse Proportion through Arduino and IoT is a hands-on webinar designed for high school through introductory college STEM educators seeking to make algebra tangible and relevant. Led by instructor Marlon Matilla, this session demonstrates how applied mathematics, electronics, and IoT technology can be seamlessly integrated to bring inverse proportional relationships to life.
Viewers will explore a classroom-ready activity using an Arduino Uno R4 WiFi, basic circuit components, and ThingSpeak for real-time data visualization. By constructing a simple circuit and collecting live voltage and current data, students observe an inverse relationship—current decreasing as voltage increases—while power remains nearly constant. This concrete investigation provides a compelling, data-driven example of the model I ∝ 1/V, bridging abstract equations with observable physical behavior.
The webinar highlights instructional strategies that promote mathematical modeling, technical literacy, and evidence-based reasoning. Attendees will see how IoT tools transform students from passive learners into active experimenters who measure, visualize, and interpret data collaboratively. By situating inverse proportion within an authentic engineering context, this lesson strengthens algebraic understanding and illustrates how mathematics underpins energy systems, control processes, and real-world technology—making math both meaningful and memorable.
