What is a high speaker?

You can not use MP3 files on an arduino SD card, you have to have a card or shield that will play MP3 files.

That's far too generic a question for a very intense and complex topic. Here's an example of an MP3 project. The first two lines read: 'What do you get if you cross an Arduino Mega, an MP3 decoder, an SD card, and a nokia LCD? If you throw in several hundred hours of programming, and a few thousand lines of code, you get an MP3 player smiley-grin.'

Already you see that it actually takes 3 devices beyond the Arduino to do it.

There are MP3 shields, they're more plug-n-play, but you apparently want to roll your own.

Here's more info: Google

Happy reading! :slight_smile: Now after all that if you think you want to do one, and you think you understand a lot of it, and you have a problem, then ask a -specific- Q and you'll likely get a very helpful answer. Or at least more info about how to figure out and troubleshoot things.

What do you mean by that?
What sort of output does this "digital receiver" have?
Have you a link to this device?

You need to be much better at asking questions.
