our project is infraredheadfone
we tried to send directly the audio signal, but actually we have a problem that IR LED and detctor should face each other ( it gives a distance o arround 1 meter but the MUST FACE EACH OTHER DIRCTLY)
note we are using te detetor thatlooks like a LED ( black one and have 2 legs)
So we knew that we have another detector ( have 3 leg , and X shape ), but we knew that it'sworking on 38KHz range which is above audio range............so we must have a modulation
so noww what modltion souldwe use, we need advices and CIRCUITS, we hav no time .. project delivery in 2 days please heeelp
