Choose your own
It's time to add some sound effects to your walking stick! You can adapt existing audio files from your computer for use in this project, or audio clips and sound effects can be downloaded from sites like http://soundbible.com/ or https://freesound.org/.
The Imperial March theme from Star Wars is a good example to start with (courtesy of archive.org).
Prepping your Audio
You will need to convert the files to the appropriate format for microcontroller use. See this guide on how to convert audio files.
Your audio file must be named something like file_name.wav, make sure that it matches what's written in the code.
Trimming and Exporting your Audio
Follow the steps below to select a portion of any audio file you want to play.
Import your audio file of choice into Audacity.
Click and drag to select the portion of the audio file you want to select.
If your audio has two channels, use the "Mix Stereo Down to Mono" function to compress it down into a single track.
