Item An Alternative to Vending Machines(Видавництво Львівської політехніки, 2023-02-28) Lozynskyi, Yurii; Yurchak, Iryna; Lviv Polytechnic National UniversityIn this review article for a smart vending refrigerator, the contours of the future device are thought out and outlined and all its advantages are described. This device will be controlled using Computer Vision and some other features. The main control unit will be Raspberry PI, since it is the best for this device. Also, a web application was developed in which the user registers, and the application itself transmits the user's information through an API that will be developed to communicate with the web server, and the web server will store this information. This article will analyze the systems that have been already on the market and their pros and cons, as well as consider the design, implementation and functionality of a smart vending refrigerator. Also, the paper will consider key requirements for this system, technologies used, and approaches to integration with existing infrastructures. This design plays an important role in providing comfort and productivity in various fields of activity and can be applied in many areas.Item Smart information board based on PSOC 6 MCU(Видавництво Львівської політехніки, 2022-06-06) Lozynskyi, Yurii; Torubka, Taras; Lviv Polytechnic National UniversityNowadays, the development of electronics and related technologies is very fast. An extremely significant role in the life of moder society is took by information output devices, the development and modernization of which is an urgent task. Using the idea regarding wireless control of remote devices, an information board with remote control was developed. This article provides a reader with the development of universal information board which customers will be able to assemble for the dimensions that they need. The created device displays text news from websites, displays time and important messages. For the convenience of updating information and automation – the board should have WiFi with Internet connection. The information board is a great way to receive news quickly, without using other means to obtain information. The information board is designed on the CY8C624ABZI-D44 microcontroller. Also, important structural elements of this board are: buffer chip – SN74ALS244CN, LED matrix control chip – MAX7219, LED matrix – 1088AS and WiFi module – LBEE5KL1DX. The functional diagram of the module 1088AS and MAX7219 connected to PSoC 6 has been designed.
