Using Arduino in Physics Teaching: Arduino-based Physics Experiment to Study Temperature Dependence of Electrical Resistance

Abstract

Nowadays, the rapid developments in science and technology have an impact on education as well as on all gear units. The integration of technology into the education process offers effective opportunities, particularly in the fields of STEM (Science, Technology, Engineering and Mathematics). In this context, Arduino platform has started to be used as a low cost, easy to use microcontroller in physics teaching. In this study, an Arduino-based physics experiment that can be used in physics laboratories was designed. We have used Arduino platform to study temperature dependence of electrical resistance and to define the temperature coefficient for a conductor. Experimental data were collected using the Arduino ohmmeter and a temperature sensor. The resistance-temperature curve obtained is in the expected character and the temperature coefficient is in the expected value. With this experiment, the student can easily observe the temperature change of the conductor's resistance and calculate the temperature coefficient of the resistance. The Arduino-based apparatus is presented as a simple and low cost alternative to physics laboratories.

Açık Kaynak Kodlu Yazılımlardan Scratch, Arduino ve Python Kullanımı Hakkında Öğrenci Görüşleri

“…Robotik kodlama öğrencilerin yaratıcılıklarının ve araştırma tutumlarının gelişmesine katkı sağladığı gibi problem çözme, soyut düşünme, eleştirel düşünme ve işbirlikli çalışma gibi üst düzey becerilerinin de gelişmesini sağlamaktadır (Lye & Koh, 2014;Sarı & Kırındı, 2019). Ayrıca robotik kodlama sayesinde öğrencilerin programlamayı daha kolay ve hızlı bir biçimde öğrenmesi ve motivasyonlarının artması söz konusudur (Resinovic, 2015).…”

Development of Arduino-Based Rotating Wheel as a Physics Learning Media of Circular Motion

“…Nevertheless, understanding the concepts of Arduino requires the learning of some programming experience, and the product's open -source nature fosters cooperative learning (Organtini, 2018). Arduino is popular in physics experiments because it is inexpensive, flexible, simple to implement, and allows for rapid data collection (Sari & Kirindi, 2019). The use of Arduino in physics experiments includes dynamic fluid material pitot tube props and venturimeters (Herdayanti, Rahmatsyah, & Manurung, 2020), static fluid viscosity materials that are related to the use of ICT.…”
