Adafruit Audio FX Sound Board - WAV-OGG Trigger with 16MB FlashWould you like to add audio sound effects to your next project, without an Arduino+Shield? Or maybe you don't even know how to use microcontrollers, you just want to make a sound play whenever you press a button. What about something that has to be small and portable? You are probably feeling a little frustrated: it's been very hard to find a simple, low cost audio effects trigger that is easy to use and does not require any programming UNTIL NOW!
Would you like to add audio/sound effects to your next project, without an Arduino+Shield? Or maybe you don't even know how to use microcontrollers, you just want to make a sound play whenever you press a button. What about something that has to be small and portable? You are probably feeling a little frustrated: it's been very hard to find a simple, low cost audio effects trigger that is easy to use and does not require any programming
UNTIL NOW!
Don't get me wrong, I love the MP3 Music Maker shield, and our Wave Shield is a dependable classic. But you still need to get an Arduino involved. There's all sorts of tricks with ISD chips or recordable greeting cards, but they never sound any good. So after a lot of engineering and tinkering we've come out with the Adafruit Sound Board, the fastest way to add audio effects to a project! We think this is the best sound board for props and costumes!
The Sound Board has a lot of amazing features that make it the easiest thing ever:
- No Arduino or other microcontroller required! It is completely stand-alone, just needs a 3 to 5.5VDC battery
- Small - only 1.9" x 0.85"
- Built in storage - yep! you don't even need an SD card, there's 16MB of storage on the board itself. Good for ~15 minutes of compressed stereo, and maybe a couple minutes of uncompressed stereo. Double that if you go with mono instead of stereo.
- Built in Mass Storage USB - Plug any micro USB cable into the Sound Board and your Windows computer, you can drag and drop your files right on as if it were a USB key
- Compressed or Uncompressed audio - Go with compressed Ogg Vorbis files for longer audio files, or uncompressed WAV files
- High Quality Sound - You want 44.1KHz 16 bit stereo? Not a problem! The decoding hardware can handle any bit/sample rate and mono or stereo
- 11 Triggers - Connect up to 11 buttons or switches, each one can trigger audio files to play
- Stereo line out - Headphones, powered speakers or even wire up one of our amplifiers to make loud sounds. We also have a version with built-in stereo speaker amplifier
- Five different trigger effects - by changing the name of the files, you can create five different types of triggers which will cover a large range of projects without any programming
What do we mean by trigger effects? Well, depending on your project you may need to have audio play in different ways. We thought of the five most common needs and built it into the Sound Board so you just rename the file to get the effect you want. See the product tutorial for more details
- Basic Trigger - name the file Tnn.WAV or Tnn.OGG to have the audio file play when the matching trigger pin nn is connected to ground momentarily
- Hold Looping Trigger - name the file TnnHOLDL.WAV or .OGG to have the audio play only when the trigger pin is held low, it will loop until the pin is released
- Latching Loop Trigger - name the file TnnLATCH.WAV or .OGG to have the audio start playing when the button is pressed momentarily, and repeats until the button is pressed again
- Play Next Trigger - have up to 10 files play one after the other by naming them TnnNEXT0.WAV thru TnnNEXT9.OGG. Will start with #0 and each one on every momentary button press until it gets through all of them, then go back to #0
- Play Random Trigger - just like the Play Next trigger, but will play up to 10 files in random order (TnnRAND0.OGG thru TnnRAND9.OGG) every time the button is pressed momentarily
The sound board is designed to be simple: it does not have polyphonic ability, can't play MP3's (MP3 is patented and costs $ to license, so this board uses the similar but not-patented OGG format, there's tons of free converters that will turn an MP3 into OGG), isn't reprogrammable or scriptable, and you can't have any other kind of trigger type. However, there's a good chance the project you want to make will work great.
We designed this board specifically for people who wanted to make props, costumes, toys, and other small portable projects. Check out the tutorial for all the powering options, you can power from 3-5VDC so a 3xAAA battery pack or a LiPoly battery will work well. You can even use our LiPoly backpack to fit on top for an all-in-one rechargeable effects board.

Great Quality for the Price
Size: 100 Count (Pack of 1)
Love these paper plates. They’re sturdy, microwave-safe, and hold up well without getting soggy or folding easily. Great for everyday use and cleanup is super convenient. Good value for the price and reliable for meals and snacks.

Nice and sturdy!
Size: 300 Count
This was our first time to try the Amazon Basics Everyday Plates. I typically purchase paper plates in bulk from a big box club store. These are just as good, if not better! They are thick and sturdy, and hold up well. The price point it also better!
My only negative is the design on the plate isn’t the most appealing. I think it’d be better if the design was limited to just being on the edge, and not across the entire plate.

Great Size, Strong Enough for Everyday Use, and Worth Reordering
Size: 300 Count
I reorder these regularly, and that really says the most. They’ve been consistent, practical, and a good value for what you get.
They’re strong enough to handle normal meals without feeling like they’re going to give way. I’ve had no issues using them for everyday food, and they hold up well as long as you’re using them as intended.
I also like the size. They’re a little over 8½ inches, which works well for most meals. If I have something heavier, I can put a plate holder underneath, and these still fit just fine.
The print/design is simple, which I don’t mind at all. I’m more concerned with how they perform, and these do what I need them to do.
I’ve used name-brand paper plates before, and for my everyday use, I feel like these compare very well, especially considering the price.
I’ll also be honest—paper plates just make sense for me. I tend to drop things because of how my hands work, so
this helps prevent broken dishes and the cleanup that comes with that. Plus, it definitely cuts down on doing dishes.
Overall, these are reliable, affordable, and something I’ll continue to reorder.

Great Everyday Paper Plates for the Price
Size: 100 Count (Pack of 1)
For around six bucks, getting 100 microwave-safe paper plates like this is a really good deal. Also, they’re actually pretty good quality. They can hold a decent amount of food and they don’t get all soggy or start dripping through the bottom halfway through eating. The soak-proof part is legit.
Another thing I liked is the design. The white and green looks simple but nice, and they honestly just look better than a lot of the random cheap paper plates out there. I’ve been using them pretty regularly for quick meals and throwing food in the microwave, and they’ve been really convenient.
I will say, if the food is extremely hot, the bottom of the plate does warm up pretty fast since the plates are somewhat thin underneath. Sometimes using two plates instead of one helps with that. Aside from that though, they’ve been excellent. For the amount you get, the quality is genuinely solid and they’ve held up really well for everyday use. Amazon Basics definitely nailed these. 100% would recommend them.

Worthwhile purchase
Size: 300 Count
Could be a tad more sturdy, maybe higher sides however still recommend; at the price/ quantity, the shear convenience, they burn easily in the firepit, and save on water/soap.
