Design, Implementation, and Performance Evaluation of a Simple Pendulum Dynamics Experimental System Based on Arduino

Year: 2025

Type: article

Abstract: This study presents the design, implementation, and evaluation of an Arduino-based system for simple pendulum experiments. By integrating an electronic control system with an infrared sensor, the instrument minimizes human-operation errors and environmental fluctuations, thereby enhancing measurement performance. Experiments using two string lengths (0.2 m and 0.4 m) and both automatic and manual methods show that the electronically controlled system provides superior accuracy and consistency. The automatic measurements produced a maximum period deviation of only 0.01 s, compared to 0.38 s and 0.30 s manually, with gravitational acceleration deviations as small as 0.02 m/s² and 0.01 m/s². These results confirm the system’s improved precision and reliability, demonstrating its effectiveness as a tool for physics experiments and technology supported learning.
