I want to connect a Wiimote. I'm running natty and would like to control an audio-player with my Wiimote. Is that possible?

Edit: Rinzwind tipped me off on a launchpad project called "wiican". Apparently it is implemented as an indicator applet and allows to customise your wii-actions. You could bind e.g. amarok -t to a wiibutton.

You're in luck, and you don't even know how much. It took me a while and a bit of research but: I wrote a script to do just that a while back. It works with Amarok and Totem, though it could easily be modified to control other players (provided they have a command line interface). Give me a few minutes to write a few comments together. Then I will edit this answer and post it.

  • Features:
    • Check battery status of the Wiimote.
    • Switch an led on the Wiimote.
    • Start Amarok.
    • Pause/contiue playing.
    • Skip to next/last track.
    • Control the system volume over alsamixer

You will need python and python-cwiid Install python-cwiid / sudo apt-get install python-cwiid installed. You can do that while waiting.


Blow is the script. Just run it in a terminal.

"""A Wiimote script to control totem and amarok under Ubuntu.

Provides a rudimentary interface to:
-Check battery status of the Wiimote.
-Switch an led on the Wiimote.
-Start Amarok.
-Pause/contiue playing.
-Skip to next/last track.
-Control the system volume over pulseaudio

Needs the package 'python-cwiid', 'amarok' and or 'totem' to be installed.

Wow. Thanks a lot. You're the killer! A GUI would have been nice too but nevermind. It's perfect. –  jordannormalform Jun 13 '11 at 0:33
Glad you like it. A gui would be overkill for just toggling a led and query the battery status. But feel free to write it on your own. –  con-f-use Jun 13 '11 at 0:39

There is also a GUI program that sits on the system tray, called "Wiican". I used to use on previous versions of ubuntu before 11.04 (Natty) but now I can't seem to know how to install it with the PPA found at https://launchpad.net/wiican

It just connects and configures buttons as you wish, yet not perfect but I would call it great

will update the post once I find out how to install.

Edit: I was able to find a package at this link
