Abstract
The development of science and technology is inseparable from the availability of hardware and software. One of its uses is teaching aids in physics practicum, especially simple harmonic motion. Digital technology can shorten the time in the implementation of practicum in the field. This study aims to design a simple harmonic motion practicum tool using Arduino-Uno based on IR obstacle sensors. Data is collected using a small angle of 100 with variations in the number of waves and time obtained. The results will be displayed on the LCD. This study also compares the results of recording digitally and analytical calculations. Based on the data obtained, the digital calculation is almost the same as the analytical calculation and shows a constant gravity value.
