A Low Cost Of Simple Pendulum Experiment Apparatus Based On Ultrasonic Sensor And Arduino Microcontroller

Abstract

Simple Pendulum is a basic physics experiment about observation of harmonic oscillation motion. Generally, this experiment is performed with manual measurements and observations that are less efficient. In this paper describe numerical simulations of Simple Pendulum motion based on Python 2.7. The experimental system of real-time Simple Pendulum based on HC-SR04 Ultrasonic Sensor, Arduino microcontroller and the interface using Python 2.7. The experimental results show good agreement when compared with the numerical simulations. The advantage of this system is open source that makes physics experiments easier and low cost.

Development of a computer-based simple pendulum experiment set for teaching and learning physics

“…Our results support the findings of other scientists (Khairurrijal et al, 2012;Pili and Violanda, 2019;Sanjaya et al, 2018;Sinacore and Takai, 2010;Yulkifli et al, 2018) who used simple pendulum motion experiment set to calculate the gravitational acceleration (g) in different places. One study in New York (USA) (Sinacore and Takai, 2010) used pendulum, telephone pickup, and sound card oscilloscope to calculate the g-value and their calculated g-value was 9.774 m/s 2 with an error of 0.3%.…”

“…A study in Indonesia (Khairurrijal et al, 2012) calculated g-value by using infrared transmitter and phototransistor receiver electronic circuit and their g-value was 9.77 ± 0.03 m/ s 2 with an error of 0.1%. Another study in Indonesia (Sanjaya et al, 2018) calculated g-value by using an HC-SR04 ultrasonic sensor, Arduino microcontroller, and the computer interface, and their calculated g-value was 9.811 ± 1.067 m/s 2 . Yulkifli et al ( 2018) calculated g-value in the same country by using both manual and digital tools.…”

“…Through this type of experiment, students obtain more accurate physics concepts compared to the conventional teaching method. These computer-based experimental sets can include various sensors, including photogate sensor (Yulkifli et al, 2018), ultrasonic sensor (Cutnell and Johnson, 2010;Galeriu et al, 2014;Pili and Violanda, 2019;Sanjaya et al, 2018;Tong-on et al, 2017), and infrared sensor (Musik, 2014(Musik, , 2017, which makes physics learning more comfortable for the student.…”

“…A low-cost experimental set could be developed in computer-based experiments by using an Arduino board and a computer (Musik, 2017;Sanjaya et al, 2018;Tunyagi et al, 2018). This experimental set is cost-effective and easily handled.…”

Development of an educational low‐cost and ESP32‐based platform for fundamental physics

“…Indeed, it is undeniable that major shortcomings in the teaching of fundamental physics can be remedied by adopting a practical learning approach. However, the high cost of modern educational equipment [2,[5][6][7]15] makes using them nonoptimal solution, technologically and financially, for the majority of educational organisms, especially in Third World countries. These constraints often push teaching practitioners to innovate and develop new approaches, alternatives to traditional methodology and tools, based on flexible and educational laboratory experiences with accessible material.…”
