Grana-cash: desenvolvimento de um jogo de educação financeira baseado em sistema embarcado e aplicativo móvel

Abstract

This work presents the development and validation of a board game focused on teaching financial literacy, integrating embedded systems and a mobile application. Based on the guidelines of the Brazilian National Common Curriculum Base (BNCC) and the Brazilian Financial Education Olympiad (OLITEF), the project aims to incorporate gamification into learning. The methodology consisted of developing an embedded system based on the ESP32 microcontroller platform and an RFID sensor, and a mobile application responsible for the game logic, financial balance control, and displaying challenges. For validation, functionality and application tests of the game were carried out with 20 volunteers, predominantly high school students. The results of the functionality indicated that the use of the Wi-Fi protocol (Access Point mode) overcame the connectivity limitations of Bluetooth, ensuring stable communication between the board and the application. In the pedagogical and usability evaluation, a high engagement rate was obtained, as evidenced in the graphs, and there was also an improvement in the understanding of concepts such as inflation, liquidity, and investment risks. In conclusion, the integration between mobile devices and gamification strategies proved effective, providing an interactive teaching tool that promotes active learning and student motivation.
