This is web page of Libor Kramoliš's GDD 2011 Arduino/ADK project.


This is Libor Kramoliš's GDD 2011 Arduino/ADK project. It is small fountain. It reproduces music by water. Music is requested via Twitter. Tweet has to contain #lapardon tag and music notation placed between brackets [ and ]. Supported note characters are 'cCdDefFgGabh' and rest (pause) character is '|'.


LaPardon Twitter

Do you want to request LaPardon application to "play" your music? Tweet it. It's easy. Follow next rules:

  • Use tag #lapardon - the tag is searched by Android application
  • Music notation is placed between brackets [ and ] - any other text outside is ignored
  • Supported note characters are 'cCdDefFgGabh' - while upper case chars means sharp variant (Cis, Dis, Fis, Gis)
  • Rest (pause) character is '|'
It is not possible to change note or rest durations. There is just one fix duration for all notes. Keep in mind. ;-)


  • One octave [cCdDefFgGabh] #lapardon
  • Up and down [cCdDefFgGabh | hbaGgFfeDdCc] #lapardon

Twitter Widget

On the right side of this page, you can see two Twitter Widgets:

  • LaPardon Runtime - LaPardon application tweets about it's runtime, what is going on
  • LaPardon Requests - your LaPardon playing requests with tag #lapardon

LaPardon House

Just touch big G on the house and first playing request from a queue is processed. ;-) See green LED that blinks during playing.



Sources for Android, Arduino and also for AppEngine (AAA sources ;-) ) are available on GitHub -


Build of Android application is available here.


Excuse me. I'm not a musician. I'm not Android developer. I'm neither Arduino developer.

But I love technologies and this was just a challenge! ( Maybe too big. :-o )

My Family

This project is dedicated to my family because they lost my time I spend on LaPardon activity. They also created beautiful LaPardon house.
