Robot Project

I have a question about building a wireless PC to speakers setup. I'm enrolled in a class that require a very basic robot project. Our group has decided to take an RC car and add some stuff to it like a streaming camera and some speakers. We’ve got most of it figured out, but the speakers are a bit difficult. We want to be able to stream audio wirelessly from a PC to the speakers on the vehicle at a range of about 75 feet. I’m thinking that Arduino would be the best way to do this but am not really sure as I don’t have much experience with it. Is there a way to attach an antenna to an Arduino board then stream the signal to speakers? Is there a better method to stream audio like this?

Thanks, Kyle

You might be better served using a small FM radio on the car, and an FM transmitter like used with an Ipod or similar.

Something like one of these:
