"基于AT89S51单片机的音乐盒设计与实现"

This music box design is based on the AT89S51 microcontroller and utilizes a buzzer to play songs with consistent and smooth tones. The main design modules include a digital tube display section, a function keyboard section, a buzzer for the voice, and a section for colored lights. The digital tube display uses a common anode digital tube that is controlled by the microcontroller to display the song numbers. The function keyboard utilizes button switches and allows for the control of the song playback order and the ability to pause the playback. The buzzer is used to play the songs, and the colored lights are represented by regular light-emitting diodes that can produce single-color steady or flashing effects. This design requires knowledge of programming the microcontroller using KeilC51 programming software, simulating the design using PROTEUS microcontroller simulation software, and a basic understanding of electronic engineering. The programming software is used to create the program, which is then downloaded onto the microcontroller. The program generates square wave signals through the I/O port to drive the buzzer and produce different tones for playing songs. In summary, this music box design utilizes the AT89S51 microcontroller and a buzzer to play songs with consistent tones and smooth playback. It also includes features such as a digital display, a function keyboard, and colored lights. The design process involves programming the microcontroller, simulating the design, and finally creating the physical prototype. Key components of the design include the AT89S51 microcontroller, square waves, and tones.
