This paper presents a practical way to discover the laws of gases via a laboratory exercise. The instruments to be used include an Arduino UNO microcontroller board accompanied by a BMP 280 digital pressure sensor. The goal is to create a manometer of general use, one that can be achieved easily with the use of the above sensor that measures barometric pressure and a simple syringe. The students have the opportunity to learn and combine knowledge from physics and computer science in an exciting way.
In recent years, the use of Arduino microcontrollers as measuring devices in physics labs has increased for a number of reasons. Among their advantages is their ability to make fast and precise measurements at especially low cost.1 Arduino has a large support community that makes a large supply of relevant material, such as tutorials and examples, available. This encourages students to learn almost autonomously....
