I've found that coming from my 3.3v Arduino Pro, it needs 100ms to get the triggerĭelay( 100) // hold the pin low long enough to trigger the board may need to be longer for consistent triggeringĭigitalWrite(pin, HIGH) // bring the pin high again to end the activationĪ simple trigger for the Adafruit Audio FX Sound Boardįor complete info on the sound board, see What I'm Doing Here PinMode(LED, OUTPUT) // Make the LED pin activeĭigitalWrite(pin, HIGH) // Set the pin high as the default stateĭigitalWrite(pin, LOW) // bring the pin low to begin the activationĪccording to the documentation, the Audio FX board needs 50ms to trigger. # define BUTTON 2 // put a simple button on pin 2 to enable/disable sound playback # define LED 13 // Most Arduinos have an LED on pin 13 Sound Board via a USB external battery for the initial tests, and the Arduino via the FTDI cable.įor later tests, I powered the Sound Board via the Arduino's VCC (3v) pin directly. Was connected to trigger pin #0 of the Sound Board, and I tied them to a common ground.

This is a simple test of a direct trigger of the Audio FX Sounds Board from an Arduino.įor my test, I used an Arduino Pro Mini running at 3.3v & 8mHz. For complete info on the sound board, see

Play Random Trigger - just like the Play Next trigger, but will play up to 10 files in random order (TnnRAND0.OGG thru TnnRAND9.// A simple trigger for the Adafruit Audio FX Sound Board.

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 Next Trigger - have up to 10 files play one after the other by naming them TnnNEXT0.WAV thru TnnNEXT9.OGG.

OGG to have the audio start playing when the button is pressed momentarily, and repeats until the button is pressed again

Latching Loop Trigger - name the file TnnLATCH.WAV or.

OGG to have the audio play only when the trigger pin is held low, it will loop until the pin is released

Hold Looping Trigger - name the file TnnHOLDL.WAV or.

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.

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. What do we mean by trigger effects? Well, depending on your project you may need to have audio play in different ways. 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.We also have a version with built-in stereo speaker amplifier Stereo line out - Headphones, powered speakers or even wire up one of our amplifiers to make loud sounds.11 Triggers - Connect up to 11 buttons or switches, each one can trigger audio files to play.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.

Compressed or Uncompressed audio - Go with compressed Ogg Vorbis files for longer audio files, or uncompressed WAV files.

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.If you don't need as much space, we also have a 2MB version. Double that if you go with mono instead of stereo. Good for ~15 minutes of compressed stereo, and maybe a couple minutes of uncompressed stereo. Built in storage - yep! you don't even need an SD card, there's 16MB of storage on the board itself.No Arduino or other microcontroller required! It is completely stand-alone, just needs a 3 to 5.5VDC battery.The Sound Board has a lot of amazing features that make it the easiest thing ever:
