Implementación de un prototipo para reproducción de canciones mediante tarjetas rfid y aplicación móvil.

Abstract

In this Curricular Integration Project, we develop the implementation of a prototype focused on a music player using RFID technology and a mobile application, to improve the interaction with the user. To meet the objective, a study of the electronic elements necessary for the optimal functioning of the prototype was carried out, and a comparison was made between different platforms that allow the connection of the prototype with the Internet, to find the most viable solution for the use of a mobile application linked to the device. The first part consisted of analyzing the components used, for which different elements were technically compared to choose the optimal elements for the device. The main elements that were chosen are the ESP32 microcontroller, this device was chosen because of its affordable price, since Arduino has similar devices, but at higher prices, the RFID module RC522 and the DFPlayer Mini module. On the other hand, a PAM8403 amplifier was added to improve the audio of the device and the Arduino Cloud platform was also chosen for the development of the mobile application. Then the circuit design and programming necessary for the functions of the prototype was performed. Technical aspects were taken into account so that the connection between modules is correct, in order to avoid damage to the devices and that the prototype can be scalable, also in this part simulations were performed with breadboard until the device obtained proper operation, in order to assemble the prototype and perform the analysis of final results. Based on the results obtained, it was concluded that the design and the electronic elements used in the implementation of the prototype were appropriate for the implementation of the music player using RFID technology and a mobile application.
