there a alot crap in my code i know 
but im testing (sry)
Im making a bomb, for some airsoft play(maybe it easy to get my Q)
I will try to explain what my problem is. i "just" need some help on witch command i shall use and how they work.
you enter a rigth code, then you enter ect 10 (for the time, in minuts you have to disarm the bomb)
then efter 10 (minuts) it go off.
If you enter the rigth code before it goes off, it shall stop the timer(resert) and start from beginning.
Hope it helped ?
