This is a showcase for a standalone sound machine powered by arduino uno v3 and dfplayer mini. Different sounds are loaded onto a TF card and are cycled through by pressing an input button.
Arduino code is available is in main.ino.
The board does serial communication with dfplayer mini. See wiki.
A noise generating script is available in noises/generate.py. It generates white, pink, blue, violet, and red (brownian) noise. There is also a makefile to automatically generate and convert to mp3 (required format for dfplayer mini).
More audio tracks are included in the sounds/ directory. These were collected from www.pixabay.com, and then edited individually to seemlessly loop.
