One of the contemporary trends in the development of physics teaching is its integration with computers. Introducing computers and microcontrollers into the teaching of physics opens up completely new possibilities for explaining different physical phenomena. Microcontrollers allow the experiment to be brought back to the focus of physics teaching in a new and different way that is far more contemporary and more receptive to new generations of students.

In the 21st century, the use of renewable resources has been propagated by the specter of climate change and its associated impact. Renewable energy technologies have been deployed at a high rate and show a significant potential to become a major player in the electricity supply in next decade. PV systems have experienced a significant growth in their rate of deployment as an alternative to conventional power sources. This study presents the modeling and simulation of a 25 kWp solar power plant in Čačak, Serbia. The power plant is situated on the roof of the Science and Technology Park Čačak. The model was developed using System Advisor Model (SAM) software. SAM was used to analyze the technical performances of based on local weather conditions and all the system components of installed photovoltaic system. The model was validated by comparing its predictions with the actual plant data. The proposed predictive model can be used to characterize power plant performance as well as analyze and evaluate the system's efficiency.

Studying the dynamic behaviour of objects or systems in response to conditions cannot always be easily or safely applied in real life. Computer simulations in engineering are very important as it solves real-world problems safely and efficiently. It provides an important method of analysis which is easily verified, communicated, and understood. Across industries and disciplines, simulation modelling provides valuable solutions by giving clear insights into complex systems. A system presented in this paper is a pneumatic sheet metal bending laboratory setup. An electro-pneumatic motion control of this system is modelled and simulated in FluidSim software. This system is also physically built using main pneumatic and electrical components with PLC. Described laboratory setup in this paper was used in the education of students and significant enchantment in the understanding of how similar systems work was noticed.
