"AT89C51单片机电子琴设计说明书"

w type of keyboard instrument. It plays an important role in modern music. The single-chip microcomputer has powerful control functions and flexible programming implementation characteristics, and it has been integrated into modern people's lives, becoming an irreplaceable part. This paper focuses on using the AT89C51 single-chip microcomputer as the core control component to design an electronic organ. The single-chip microcomputer is used as the main control core, and it is combined with keyboard, speaker and other modules to form the core control module, which has 16 keys and speakers. The system runs stably, and its advantages are simple hardware circuit, perfect software function, reliable control system, high cost performance, and practical and reference value. In conclusion, this electronic organ design has practical significance for modern music learning and electronic instrument development.
