"基于AT89C51单片机的多功能音乐盒设计与实现"

Li Kun, a graduate student from the Computer Science and Technology Department of Shaanxi University of Technology, has completed a design project for a music box based on the AT89C51 series single-chip microcomputer. This project involved the use of hardware circuitry and software programming to create a multifunctional music box capable of playing two songs and displaying three different LED patterns. The music box is comprised of a key circuit, a reset circuit, a clock circuit, and a buzzer. Two buttons control the music box, with one button used to switch between songs and the other used to change the patterns of the 8 LED lights. When a song is played, the buzzer emits a specific tone corresponding to the melody, and the corresponding LED lights up in synchronization. The design process included programming the music box using the KEIL software and simulating the hardware using the PROTEUS software to streamline the development and debugging process. This approach saved time and resources while ensuring the functionality and reliability of the final product. Overall, Li Kun's project demonstrates a successful application of single-chip microcontroller technology to create an innovative and interactive music box. This design project offers valuable insights into the practical implementation of microcontroller-based systems and serves as a testament to Li Kun's skills and knowledge in the field of computer science and technology.
