In this paper, based on circuit design and microcontroller programming, a electronic tuner based on the 89S52 microcontroller was designed. The tuner can accurately adjust the pitch of the instrument and has the characteristics of portability, simplicity, and practicality. The paper introduces the principle, design process, and implementation method of the tuner, and tests and analyzes the actual effect of the tuner. Through this research, an effective tuning tool for instrument enthusiasts and music producers can be provided, and a practical case for microcontroller application can also be provided.
