Play 3 audio samples with arduino

Hi,

I have a small question, which I can't seem to find the answer for on the web.

For a project I need the arduino to play 3 possible audio samples based on the input of a sensor. To put it simple:
if sensorval < 100 then play audiosample1
if sensorval > 300 then play audiosample2
if sensorval = 200 then play audiosample3

However, i can't seem to find how to play multiple audio sample with the arduino (preferrably the mini). I don't want generated tones by the pcm, but samples based on MP3's I have now. All the samples are approx. 2 to 3 seconds long. I found this code done by Micheal Smith (Arduino Playground - PCMAudio) which can play a pcm soundfile right of the Arduino, but that's just 1 file. Is there a possibility to do three? My guess would be that the storage on the arduino will be to small?

Sparkfun however sells MP3 boards (Breakout Board for VS1002 MP3 - BOB-00519 - SparkFun Electronics) than can play multiple MP3 files? However, can I connect this to the Arduino? And what about storage for the files? This somehow doesn't feel like the proper solution, but I'm not sure. Seems a bit overkill for just playing 3 samples? Besides, these boards are already quite big for my project, so it can't get any bigger than this...

Oh and to make things worse, i want to play this audio from small speaker, so a person 1m away would be able to hear it.

Sorry, I know I am asking a lot here. But if someone can just help me in the right direction that would help me a lot!

Have you seen Lady Ada's wave shield, although it sounds like it might be too big for your project? Adafruit Wave Shield for Arduino Kit [v1.1] : ID 94 : $22.00 : Adafruit Industries, Unique & fun DIY electronics and kits

Yes I have seen that one too, sorry for not mentioning it. Functionality wise this board would be perfect, sizewise it is way too big... :slight_smile: It would be perfect if this would have been made into an smd board. Don't have the skills however to do it myself.

So my question is, is there any possible solution like this board could provide, but then smaller?

Or is there another solution possible?
