Infrared Led Based Wireless Audio Transmitter and Receiver
Abstract :
The Wireless Audio Transmitter and Receiver presented in this paper are IR-based. The main technologies used in the technically advanced field of wireless audio are RF communications and Bluetooth (though extreme marketable audio tools acts with Bluetooth). Scheming the basic circuit for an IR Audio Link would be a nice learning experience for wireless audio transfer but would not be advantageous in comparison to the current technologies. Because IR is line-of-sight message instead of Bluetooth, it is not advantageous. i.e. without any obstacles both the receiver and transmitter must always face one other. Furthermore, the range could not be as extensive as a regular Audio via Bluetooth wireless. None the less, using easily available components let me create a basic IR audio link circuit for the purpose of understanding.
