Hi everyone!
Here I am, Marc, an arduino newbie. Long time electronic enthusiast (doesn't mean my electronic skills are much higher than my coding ones...) and new comer to ucontroller programming.
I am currently trying to do a simple event sequencer.
I wrote a couple of lines to test and confront myself with reality 
And of course I did run into some problems!
So here they are :
1 : I intended to make a 3seconds button pressed condition but when I press it multiple times, it seems I block the sketch and even though the led respond (it blinks with the press of the button) I cannot "unblock" the sequence
2 : sometimes the timed action (10seconds in this case) doesn't do the 10seconds at all. It varies from 2 to 10seconds.
And it usually varies more when I press the start button multiple times (in order to try the condition).
I am a bit lost right now since I thought I had made a pretty "clear" sketch and I can't seem to see where does theses errors come from...
Thanks by advance for your help!
