This article presents a project that contributed to the computerization of the obsolete measurement and control cabinet SPS1, which is part of a test stand designed to determine the parameters of the engine in wheeled tractors. The test stand is located in the Department of Energy Systems Engineering at the University of Life Sciences in Poznań. Arduino platform was used as a built-in system, which enabled the exchange of information between the computer and the measurement and control cabinet along with the readout of analogue meter readings and the control of the engine dynamometer brake load. In order to clearly display measured parameters, proprietary applications were developed in the .NET environment, which in real time presents the results and graphs the speed characteristics of the engine. The implementation was carried out without violating the design of the test station.
