The goal of this project is to design two devices, a transmitter and a reciever, that will transmit audio using a pulse width modulated LED and filter out an ambient noise signal of 60hz produced by flourescent tube lights.
The transmitter will use an amplification circuit to boost the voltage of the audio signal in order to drive the LED. The reciever will use a band stop filter amplifier to filter out 60Hz signals and boost the voltage recieved to drive the speaker.
These transmitters are able to brodcast over 10ft to their reciever, filter out ambient light from local flourescent tubes,
