Music Player v1.0.0

I had some small Cambridge Soundwork speakers hanging around and wanted to do something with them, so I decided to use them with a RPi Zero W as a music box.


(I still have to figure out a better mounting method)

From the ReadMe:

This music player reads a folder (called 'songs') and will play the songs in alphabetical order.
Once all the songs have been played, it will restart the list.

You can Pause/Resume play, Skip to the next song, go to the previous song and stop playing any songs.

There is also a button to power off the Pi.

I designed this to allow it to be controled by an iPhone by turning on
the iPhone's Personal hotspot. To access it this way, you need to add the iPhone Hotspot name
and password to the wpa_supplicant.config file on the Pi.

This is running on Node-RED v0.20.5. with the following components and nodes:
a HiFiBerry MiniAmp hat (https://www.hifiberry.com/shop/boards/miniamp/) for an amplifier
node-red-contrib-fs-ops (v1.5.0) to get the sound file names
You will also have to install mplayer (sudo apt install mplayer) or change the play-sound node to use another player.

37%20AM

node-red-contrib-play-sound (v0.2.0) to control the playing of the songs and

an exec node running amixer to control the volume

and a second exec note to allow remote shutdown of the pi.

Here is the flow I built

Hi, really nice setup

could you tell me what a message should look like which triggers an mp3 file to play with the "PlaySound" Node ?

For Example if i want to use the command for the sox player "play /home/pi/music/song.mp3" ... how would the function node look like, which pumps the signal to "PlaySound" ?

Kind regards
Marten

I put some notes in the play-sound github page https://github.com/MattVador/node-red-contrib-play-sound/issues/6 about using aplay, don't know if they will help you or not.

figgured it out later yesterday ... so easy :smiley:
just if anyone else needs a quick example ^^
