Development of a microcontroller device for reproducing audio information

Abstract

The paper presents the results of the design, development and manufacture of a microcontroller device for reproducing sound information in the presence of a person. The description of the concept of a microcontroller device and the architecture of the system are given. The technical specification for the manufacture of the device and its software has been compiled. A prototype of the audio information playback device based on Arduino-UNO was made. In order to reduce the cost of one product, the device was upgraded and the ATtiny13A-SU microcontroller was selected as the microcontroller. An electrical principal scheme, a printed circuit board of the device and software for it have been developed. 17 operating audio information playback devices have been manufactured. A technical solution for further improvement of the microcontroller device is proposed.
