Abstract

With the development of human society, people put forward higher and higher requirements for the enjoyment of vision and hearing. A little music box can bring good memories to people and enhance people's spiritual and cultural enjoyment. The traditional music box is mostly mechanical, cumbersome and monotonous, and cannot achieve mass production. This design is a digital music box based on AT89C51 Series MCU. The music box is mainly composed of key circuit, reset circuit, clock circuit, display circuit and buzzer. Four keys are used to control the music box, two of which are used to control the playback and pause of songs, and the other two are used to control the change of song order on the LCD. When playing the song, the corresponding song corresponds to the song sequence and song name display on the corresponding digital tube. Finally, Proteus Software is used to simulate the design system and test whether the function of the system can be implemented normally.
