I have a alarm installed in my car, wich when activated outputs a ( negative 12v max current 100mA )
and just installed central locking, wich has two 12v negative inputs ( one for locking , and the other for unlocking )
I need to connect them togeter so when i activate the alarm the doors will lock automaticaly, and when i disactivate the doors will unlock ....
the bigest problem is that :
the central locking only needs a 1second puls to lock/unlock ....
u guess i need some 555timers and some relays....
please help
