During inquiry-based physics teaching there are many difficulties for which a large number of teachers do not achieve the core part of the physics class, which is the experiment that encourages creativity in students, develops critical thinking and conclusion. Problems are very common due to the lack of laboratory equipment and the lack of money to equip the cabinet. Because of this, many teachers skip practical measurements where students, based on them, can practically validate the laws of physics, but as the aspiration of contemporary teaching is knowledge which is followed by understanding, the experiments are certainly not desirable to skip. Today, at a time of extremely favorable consumer electronics, we can make use of devices from the environment to analyze and clarify physical phenomena in a simple and inexpensive way. The emergence of new generations of microcontrollers, such as the micro:bit device, enables their wider application in education, particularly as a component that we can use to demonstrate experiments in physics teaching. Also, such teaching is necessary to support with independent student projects that are a form of independent research work, in which students develop different abilities. This graduate thesis will highlight the possibilities of using a microcontroller, namely micro:bit device, within the project-based learning where the student constructs a selected demonstration experiment from physics. The result of this graduate thesis is a detailed instruction for teachers to implement such an approach to teaching physics.
