I’ve been playing with the very excellent Volumio.  Having got it all up and running, with a Hifiberry DAC and an LCD from http://andypi.co.uk/?p=351 it was pretty good. However, Volumio only allows for one playlist and the occasional song I was not in the mood for crept in.

So I wanted a skip to the next song button. Entirely possible with the Pi, and I found a guy who had done it – but his code wasn’t complete. Here are the full instructions:

Connect a switch to two spare gpio pins. I used GPIO 4 to ground.  This was useful.










sudo apt-get update

sudo apt-get install python-dev python-pip
sudo pip install –upgrade distribute
sudo pip install ipython
sudo pip install –upgrade RPi.GPIO

Then make a file – mine is called button py

nano button.py

This is the code

[code language=”python”]

TEST_MPD_HOST = “localhost”
TEST_MPD_PORT = “6600”
TEST_MPD_PASSWORD = “volumio” # password for Volumio / MPD

# Connect with MPD
client = mpd.MPDClient()
connected = False
while connected == False:
connected = True
client.connect(TEST_MPD_HOST, TEST_MPD_PORT)
except SocketError as e:
connected = False
if connected == False:
print “Couldn’t connect. Retrying”

while True:
if (GPIO.input(buttonPinNext)): # Play the next song in this play list.
print “Next track in play list”

Download it here and change the extentio from txt to py

Test the code:

python button.py

Make it run at boot – you need to edit /etc/rc.local (as root since this is the owner).

sudo nano /etc/rc.local

At the bottom, just above exit 0 we’ll add a call to our script.

python /root/python.py

Ctrl x to save

Here is a rubbish picture of the finished article.
