Technology has revolutionized physics education, offering alternative approaches to traditional methods. These alternative approaches make physics education more engaging, accessible, and aligned with the demands of a rapidly evolving landscape. In this connection, the Arduino1,2 has gained popularity as a versatile microcontroller, particularly in the field of physics education. In recent years, there has been a significant increase in the number of studies using Arduino for various physics experiments.3–13 

The exploration of the electric current–voltage (IV) characteristics of semiconductor diodes stands as a cornerstone in fundamental physics courses. This experiment, while seemingly basic, holds profound significance at the introductory level. Its educational value extends from elucidating the practical applications of diodes in diverse circuit operations to even reaching the realm of determining fundamental constants like Planck’s constant. The experiment involves applying incremental voltages across the diode and determining the resulting current. To automate and...
