Bluetooth hard drive speaker

Overview

An STC8H1k28 microcontroller is used to connect to a brushless motor drive circuit to control the rotation of the hard drive motor. The frequency of the output signal from the Bluetooth power amplifier module is acquired through the external interrupt pin of the microcontroller, and the LED is lit up and the hard drive mechanical arm swings according to the corresponding frequency.
