I'm trying to design an audio IR transmitter & receiver for a course project, and I wanted to know what would be the best/easiest method of modulating an audio signal for transmission? So far I was looking at Pulse Width Modulation using an 555 timer. Is this a simple/effective method? Is there any better or easier method? If I used a PIC microcontroller would it be significantly more complicated?
Any responses will be appreciated
