The article deals with the problem of developing a modern computer Interface to traditional installations for laboratory work on physics and search for new, active forms, methods and learning tools that would fit modern trends in the development of education and facilitate training highly professional physics teachers. Modern facilities for research isoprocesses in gases consist of a vessel, the volume of which can be changed, pressure and temperature sensors, device for processing signal from sensors. But the price for such installation is too high for educational institutions. The results of implementation of the method of use of the platform Arduino in a laboratory workshop on molecular physics as a simple and, at the same time, an effective alternative to factory equipment for the study of gas laws are given in the article. Arduino is a hardware computer platform for amateur design, basic components of which is a microcontroller board with I / O elements and Processing development environment. The article contains a description of the hardware platform Arduino Nano and pressure and temperature sensors BMP180, MS5611-01BA03, DS18B20, which are used in the installation for the study of gas laws. An important methodological aspect of laboratory work with the use of Computer and Arduino is the data processing of the experiment. Need experimentally establish a functional relationship between independent measured gas parameters: pressure, volume and temperature. In the laboratory works on the study of gas laws is proposed to use methods of statistical analysis: direct selection method functions and the method of linearization. The isochoric or isochloric process is thermodynamic process, which occurs at a constant volume. In its gases to carry out simply - it is enough to heat (cool) substance in a vessel that does not change its volume. The article describes how to explore isochoric process with the help of the developed device. The given software is a code for working with pressure and temperature sensor. Proposed methodology proved the feasibility of practical use of hardware and computer platform Arduino at the Laboratory for Molecular Physics.
