This study aims to showcase an experiment for introductory physics students that quantitatively describes the relationship between gas pressure, volume, and temperature. For this purpose, an Arduino Uno Microcontroller and BMP180 pressure sensor are used. The BMP180 can also measure temperature, so another temperature sensor is not needed. Pressure-volume and pressure-temperature graphs are plotted with the experimental setup using cheap and easily accessible materials. It can be seen that the drawn graphs correspond well to the theory. It is hoped that this experimental setup can be used by teachers in STEM activities, especially for physics courses.
