Real-Time Graphing of Simple Harmonic Motion of Mass on Springs with an Arduino Based on an Experiment Set for Teaching and Learning Physics

ABSTRCT

The real-time graphing of simple harmonic motion of mass on springs with an Arduino based on an experiment set for teaching and learning physics in high schools where students can learn from real experiences. The objectives of this study are to create and develop a real-time measurement for vertical oscillations of mass on springs using the Arduino microcontroller and the infrared sensors. This experiment set is improved from the original experiment which was used to measure the period of an oscillation of mass at various points by using signals of the output voltage of the infrared sensors and the Arduino program to record the time on the computer. The results of the experiment were relevant to the theoretical calculation. Students learned to understand the simple harmonic motion experiment of mass on springs and were able to measure the displacement functions depending on time enabling students to get concepts in physics in real-time more accurately and quickly. Physics teachers can build these experiments on their own for a low cost, and these experiments will be very useful for teaching and learning.
