Abstract
The purpose of this work is to improve the educational process in higher and pre-higher education institutions by expanding the laboratory and technical base for conducting practical and laboratory classes for the digital electronics course. The research methodology included an analytical review of modern laboratory equipment, determination of functional and technical requirements for the system, selection of the element base, circuit and software modeling in the Proteus environment, as well as integration with the LabView interface for visualization and control. Modeling of basic logic elements, simulation of analog-to-digital and digital-to-analog converters, and implementation of a USB interface for data exchange with a PC were carried out. The results of the study confirmed the system's performance in emulation mode: the stand successfully reproduces the logic of digital elements, measures analog signals, generates and processes PWM signals, and transmits information to LabView for further processing and display. The power consumption was calculated and the circuit solutions were optimized to ensure stable system operation. The originality of the project lies in the combination of simple and affordable hardware components (Arduino Nano, X9C102, LM317, LC-LM358-PWM2V) with modern methods of circuit and software modeling, which significantly reduces the cost of implementation without losing functionality. Integration with LabView provides additional opportunities for analysis, visualization, and interaction with the system in real time. The practical significance of the development lies in the possibility of using the created complex as a tool for conducting laboratory work, practical classes, and research activities in the field of digital electronics. The stand allows students to gain practical skills in working with microcontroller systems, logic elements, and converters, and teachers to effectively organize the educational process.
