Sound file trigger

Hey guys,

What would be the simplest solution to triggering small low quality audio files (wav) using arduino and triggered by RFID tags?

The files could be read from a memory card if needed but if there is a simpler way it would be better due to time constraints. Can sound files be stored on the arduino? The sound files will be played back through headphones which shouldn't pose much of a problem.

To clarify, I want to be able to assign a different audio file to each RFID tag and they will be triggered on proximity to the tags (less than a meter)

Very new to arduino and any advice would be great. Don't have an arduino yet but will have access to a couple of different types in the next few weeks. Any point in the right direction would be greatly appreciated.

Many thanks

I have used one of these mp3 player modules. It was easy to use, can drive headphones or a small speaker directly. You can use an ordinary Arduino to send it instructions, such as a Nano 3. You prepare the sounds as mp3 files on your PC and then write them to a micro SD card. The Arduino just needs to send the track number to the player over a single wire to play it.

Thanks that sounds like a viable option!

RFID tag and they will be triggered on proximity to the tags (less than a meter)

While the tag distance will be less than a meter it is likely to be about 10 to 30 mm.
