BackgroundThe Raspbery Pi 1 B board is fully capable of adding sound to your next project.
I have several Raspberry Pi 1 boards lying around not doing much since they were replaced by Raspberry Pi 2 boards.
I have decided to use them as general purpose sound generation boards in my projects.
I initially thought of playing back MP3 files over a speaker in response to serial commands.
I have now added the concept of on the fly (not prerecorded) TTS (Text to Speech).
