"基于51单片机的可控数字音乐盒设计与制作"

Based on the AT89C51 single-chip microcontroller, this paper presents the design of a controllable digital music box. The music box is a multifunctional device designed and created using single-chip microcontroller technology principles. The hardware circuit is simulated and produced using PROTEUS simulation software, and the music box source code is compiled in C language using KEIL software. The music box generates different frequency square waves by controlling the internal timer of the single-chip microcontroller, which drives the speaker to produce music with different tones. The program converts the music scores into corresponding timing constants to drive the sound devices to play pleasant music. This digital music box features five songs and three variations of LED lights. The LED lights flash in sync with the music when playing songs, and switch to the three different patterns when the music stops. Users can freely switch between songs and light patterns, with the digital display continuously showing the song and light pattern numbers. The key words for this project are digital music box, AT89C51, KEIL, PROTEUS, and digital display. In conclusion, the controllable digital music box designed in this project offers a unique and interactive musical experience for users. The combination of music, LED lights, and digital display provides a multi-sensory experience that can be customized and enjoyed by users of all ages. The successful integration of hardware and software components showcases the capabilities of the AT89C51 microcontroller and highlights the potential for further development in the field of digital music technology.
