Hi, Soranne !
As I said on the french topic of your project - http://arduino.cc/forum/index.php/topic,93067.0.html - I'm trying to reproduce the same kind of project with a PIC18F2550.
When i'll finish it, i'll share it on this topic, attached with a report. I expect that will help everybody else to adapt this project to their favorite microcontroller.
Cordially,
Watchi~
