Play Next Trigger – Have up to 10 files play one after the other by naming them TnnNEXT X.WAV up to TnnNEXT X.WAV (or. Latching Loop Trigger – The audio will start playing when the button is pressed once and repeats until the button is pressed again. Hold Looping Trigger -The audio will play while the trigger pin is held low, it will loop until the pin is released. Name the file Tnn X.WAV (or.OGG) where “ X” is the pin number you want to allocate the sound to. Depending on the project you may need to play audio in different ways:īasic Trigger – The audio file will play when the matching trigger pin is connected to ground momentarily. You can control how the sounds are triggered and which pins trigger them by how you name each file. The Sound Board has 11 trigger pins (numbered #0 to #10), which means you can connect up to 11 buttons or switches, with each one triggering a different audio file.

Audacity is free and a great way to create and edit your own sounds. The decoding hardware can handle any bit/sample rate and either mono or stereo audio. We recommend using Ogg Vorbis files for longer audio files. You can create your own sounds, t he board can play either uncompressed WAV files or compressed audio files in the Ogg Vorbis format. Always make sure you solder in a well-ventilated area or outdoors.

Solder the supplied header pins onto the Sound Board.

You can double this if you use mono instead of stereo. The built-in storage is good for a few minutes of compressed stereo audio, and maybe half a minute of uncompressed stereo. The Sound Board has 2MB of built-in storage which you load with sound effects via USB just like a USB flash drive. We’ll show you how to make low-tech pressure pad switches to trigger sounds.

Ever wished you could have musical stairs which play sound effects or work as a piano? This project uses the amazing Adafruit Audio FX Sound Board which doesn’t require any programming, making it really accessible for makers of all ages and abilities.
