Wireless Music Player Design Based on White LED Visible Light Communication

We design a music player system based on white light emitting diode (LED) in visible light communication (VLC) system, using infrared remote to control. The transmitter loads music data from the storage device, decodes it and sends it to modulate LED arrays. The receiver transforms the optical signals to electrical signals, through the PIN circuits. After the amplifying circuits manage them, they are sent to a speaker to play. At the same time, a LCD will display the information of the music playing. The test shows that the music player can play fluently a variety of formats of music files and be easily controlled by the infrared remote control.
