Posting here to save this awesome thread to my history. I'm using a trigger for the first time this year and having a sound trigger along with it would be great. The only problem I foresee is that 2 second delay...

If you are going to use Arduino for more precise control, I have had much luck with the Catalex Module.
The seller offers a small discount if you buy 5 of them, making them just under $6 with free shipping.

This is the audio module I am using in the FourBanger project, so if you download the main zip package, you will find the Arduino source code I use to call the major functions of the module via serial control. I also threw together some info (manual, .Net test app, Arduino code) into a zip and dropped it HERE.

It sounds like you have some fun projects going on!
Thanks, Mike
I just bought a couple of these myself! Looks like exactly what I need for my walk-through!

This is really cool! Thanks for sharing. Is there a way to set up three or four buttons to have three or four programmable sounds? I would like to build a costume and set it up with a few different sounds at the touch of a button. Any ideas if this will work? Bty the way, it's a next year idea.

Hi,
I do not think you will get these boards in time. it takes 2-3 weeks to mail.
the board does have buttons but when power is applied it is the first song that starts, you would have to press buttons manually.

Thanks J-Man. I'm not sure how to install it or what to install it into. I'm sure I can handle the Sound Board from Replica Props but I really like the price of this one.

Super simple. Your wav or mp3 files go onto a microSD card. 5vdc to the player, GND to pins 1-8 will trigger the respective sound file or it can be controlled via serial with a microcontroller. You will need some type of amplifier or powered speaker. There's lots of really cheap amplifiers on ebay.

j-man, I just ordered a few of these to (hopefully) hook up to an arduino. You seem fairly tech savvy. I on the other hand am not. My plan is once a beam is broken (most likely a pir) , the arduino will turn on a relay that goes to an electrical outlet (That part I have already done), which gives juice to a pneumatic solenoid. At the about the same time as power goes to the relay/solenoid, I would like the audio to switch from crickets/wind/owls etc. to a different sounds like perhaps a roar. Hopefully you can help me. I'm not sure exactly how to control this thing with an arduino. Thank you

Thanks J-Man. However, some of that is still over my head a bit for now. But that's okay, because that's one of the reasons that I am looking into this now. To get a head start before I start buying and building. Thank you for the help.

This player won't do an ambient loop, but by configuring your Arduino coding, you could get it to act similar. By knowing the length (time) of your ambient sound file, have the Arduino send a 500ms pulse to trigger that file every time it ends. In other words, if your ambient file is 1 minute long, and your ambient file is #1 on the microSD card, send a 500ms pulse to pin 1 of the player every 61 seconds. When your prop gets triggered, have the Arduino send a 500ms pulse to pin 2 of the player (your roar file will be #2 on the SD card). When your "roar" file is over, send a 500ms pulse to pin 1 again to restart your ambient file. All pins on the player are active low, meaning they need GND to activate, not positive voltage. You can also control the player via serial commands from the Arduino but that gets a little more complicated in the coding.

Thank you j-man, I'll have to fiddle with it and see what happens it doesn't sound that difficult. My next question is: the board has many pins for play/pause, forward, reverse, volume up, volume down, tx, rx, etc. Do I need to use any of those? Or is it as simple as connecting the speaker, positive, ground, and my 2 sound file pins? The data sheet is not seen for this model, but there is one I found for a discontinued model that seems practically the same. Like I said, I'm fairly new to the arduino (read dumb) so I could be missing something/everything. Thank you for all your help and advice and I'm sorry for hijacking this thread

You won't use most of those pin connections. Just power, speaker, (to your amp or powered speaker), and your 2 SFX pins. As for your Ardunino code, can't really help you there, I use Basic Stamps. Send MDFLY a message and tell them to email you the data sheet for that player.
