Displaying messages with only 7 (or 4) LEDs on a stick...

Thanks for all your infos.

I get a better view of what I'll have to do now.

Toley00, thank you for your offer about your code but... for now, I would like to make my own one (I don't like to spoil my fun) If I'm stuck, I'll ask you again.

I was just really missing this info about finding the correct "display start point" for the beginning of the movement...

If you don't want to make your own sensor, you might use one of the vibration sensor used in the alarm systems to sense glass breakage. They are adjustable so you can set the sensitivity.
