"基于STC89C52单片机的插卡式音乐盒设计与制作"

With the continuous development of human society, people's quality of life demands are increasingly high. The traditional music box brings beautiful memories, but due to the small size, low cost, fast operation, and low power consumption of the single-chip microcomputer, it is widely used. This design is based on the STC89C52 series single-chip microcomputer music box. Based on single-chip technology and principles, through hardware circuit production and software compilation, a plug-in music box is designed and produced. The key components of the music box are the button circuit, relay circuit, LCD display circuit, and speaker. Five buttons are used to control the music box, which are used to control play/pause, reset, switch to the previous/next track. The music box contains five songs on a USB flash drive. This design uses KEIL programming software to program and debug the music box source program and then download it into the 51 single-chip microcomputer for use.
