(i would if i'm in situation alarm on in alarm out situation
if the door open i don't press the correct password the alarm begin
after alarm begin if i press the correct password i'll go in situation alarm off)

this is the code

What is the question?

system · October 30, 2011, 2:14pm

(i would if i'm in situation alarm on in alarm out situation
if the door open i don't press the correct password the alarm begin
after alarm begin if i press the correct password i'll go in situation alarm off)

how i can do it ?
it isn't a simple delay(10000)

This does not make sense - rewrite it so that there is no chance of confusion.

A numbered list might work well.

system · October 30, 2011, 3:36pm

You seem to have already written a whole lot of code. Please explain what you expect it to do and what it does instead. Point of where in the code you think the problem resides.

When you explain your problem, using proper sentences (capital letters and punctuation) adds readability.

nickgammon · October 30, 2011, 11:26pm

enterpc:
this is the code

Can you post code that actually compiles? This doesn't look as if it has a hope of compiling:

    if (ON_OUT == HIGH  &&buttonState_DOOR == LOW){

(i would if i'm in situation alarm on in alarm out situation
if the door open i don't press the correct password the alarm begin
after alarm begin if i press the correct password i'll go in situation alarm off)

digitalWrite(ledPin_ALARM,HIGH);
lcd.setCursor(0,0);

I am not familiar with this coding style:

       (ON_IN   = LOW);
       (ON_OUT = LOW);

Why are you putting things in brackets?

floresta · November 1, 2011, 4:52pm

You have to break your project down into small steps and get each part working in sequence.

Use an LED to represent the alarm and a push button to represent the magnetic sensor (switch) on your door.
(1) LED on with door open and off with door closed.

Add push buttons to represent additional doors and windows.
(2) LED OFF when all doors and windows are closed, LED goes on when any door and/or window is open.
(3) LED OFF when all doors and windows are closed, LED goes on when any door and/or window is open, LED stays on even if all doors and windows are then closed.

Add a switch to arm / disarm the alarm.
(4) LED works as in (3) when the alarm is armed, LED stays off even when doors and/or window is open when alarm is disarmed.

Add a keypad.
(5) Correct sequence on keypad arms / disarms the alarm

Add an LCD display.
(6) Alarm status indicated on LCD display

Don't forget to debounce your door and window switches and your keypad.

I have tried these .I will try to describe exactly my problem

When the alarm is activated and the window open.
start the alarm siren
if I press the correct code stop the alarm siren and turn off the system (this is ok )
When the alarm is activated and door open.
Wait 10 sec and if i dont press the correct code in 10 sec, start the alarm siren.
If I press the correct code in 10 sec . Stop the alarm siren and turn off the system.
After the 10 sec if I press the correct code stop the alarm siren

The second piece is the my problem i nead a delay of 10 sec

The second piece is the my problem i nead a delay of 10 sec

Why didn't you ask that in the first place?

First figure out how many milliseconds you need to delay. Then look at the 'Blink without Delay' Tutorial.

By the way.... Two out of the three words in the title of this tutorial are misleading so you might initially think it is not of much use for your application. They are blinking an LED but this is just representing that they are doing one thing and then later on they are doing something else. They are NOT doing this without a delay, they are doing this without using the delay() routine - which is a lot different. The tutorial should really be called something like 'Wait without using delay()'.

if I understand you correctly . you're saying me to use the function millis()

Yes!

You're going to have to start posting your code correctly.
Use the # icon on the editors toolbar.
You can (and should) go back and edit your posts.
Highlight the code, then click on the # icon.

My problem is that when I open the door I need delay 10 sec i tried the millis() but nothing this is my code

I didn't find millis() anywhere in your code.

Don

yes this code work ok. It's without millis()
if i use millis() i have problem

So show us the code that doesn't work?

if (run == HIGH);

Why?

system · November 4, 2011, 9:58pm

if run == low dont digitalWrite(ledPin_alarm,HIGH);
only if run = high digitalWrite(ledPin_alarm,HIGH);

is it wrong?
