Advices on creating a arduino live radio

Development Boards Arduino

Hi guys,

I am having a problem on getting information on creating my own personal arduino live radio. After searching online for some time, i see that most of the arduino radio uses the sparksfun mp3 player. My lecturer has told me that it is possible not to used the sparksfun mp3 player and just used the speaker / arduino uno / arduino ethernet shield to get the radio to be played. As my lecturer will be away for some time, i do appreciate any help or guidelines i can follow. Thanks.

What do you mean by live radio?

My guess ... streaming "radio" {/snicker} over the Interwebz. I thought those streams were all mp3 encoded, and your base Arduino lacks the power to decode mp3 at any reasonable bitrate. So if I'm correct, the professor is not. And topping it off, the sound quality using 8 bit PWM is going to be lo-fi.

Ya, an Arduino SURELY isn’t going to sample any audio fast enough to be of any use after throwing in the code overhead for dumping it over WiFi and Arduino’s own overhead, blah blah blah.

“Lecturer”…pffffttt…They’ll give anybody a title these days…

Moreover, from the tone of the OP, I get the distinct impression that the OP is in “over his head”.

And stop calling me Shirley. :mrgreen:

BTW, the picture shows an electret microphone connected to the Arduino, not a speaker…

Hmm, i don’t get what’s going on but i understand that now the arduino needs a decoder chip too. But i am stuck as to where to go from now, what kind of chip or what other stuffs do i need to get this started? For example maybe the FM Radio Receiver module?

Why would you need that ? Are you trying to receive broadcast radio ? If so why were you mentioning the Ethernet shield or the MP3 player (decoder) ?

This 1’st thing you have to do is define, specifically, what it is that you’re trying to do. We can’t help you with that.

As was already asked above :
