Hi lainons. I need a device that can play a music file stored in a SD card/USB key(I already have the amplifier, just need an audio exit) depending on an Arduino output. The MP3 shield costs as much as a Raspberry, so which should I choose? There are cheaper alternatives? Also, I never used a Raspberry before. Thanks.

can you move the files and just run them from an iPod? it solves all of your problems.

How the hell do i control the iPod with Arduino?

He obviously does not need an iPod,he needs something with what he can complete his non-standard DIY project.

Can you use a raw output signal?

i would recommend a raspberry pi

i have and use a raspi and consider an arduino over my head from

just wondering what you're trying to build, cuz you can also buy some cheap dumbphone boards from china for like 2 bucks and they have the ability to play mp3/mp4

I saw cheap chinese screenless mp3 for $10. You can pipe into button connections with transistor and use arduino for control. Alternatively, you can buy more expensive chip, make DAC and play .wav off SD card:

But personally, I prefer simple, brain-dead solutions.

If it's between those two, you should get the Raspberry pi. It's very easy to use and multipurpose.

Why not? If you can make it to work. Also, I saw an article about making SD card logger. You might want to do a search.

There's a library for arduino that plays .wav files from an SD card, only requires a transistor, a resistor for pulldown and the speaker.
https://github.com/TMRh20/TMRpcm

It depends on what you need it for, if you want to play one sound for something, then this is good, but you have to convert the files to have a specific bitrate or they will sound like shit, I don't remember exactly because I've only used it once last year.
You'll also have to look carefully at what pins you use.
