In this paper

we design and realize a music player based on visible light communication technology.At the transmitter side

the STM32 module reads the music files and decodes them

which are sent by LED array.At the receiver side

a lens condenses the light which carries information.A PIN photodiode converts the light into the current.After that

through a trans-impedance amplifier and a filter circuit

the music can be played by a speaker.The system has on-demand function

which can achieve remote wireless control.The test results show that the transmission distance of the signals can be up to 5 m

with clear sound.And the remote control achieves a range of 10 m

which satisfy the requirement of the design.
