i just bought a arduino uno board,a keyboard a lcd screen and magnetic switches. basicly i want my arduino to act like a security alarm and as soon as someone opens the door i want the magnetic switch to tell the board that it has been triggered and it visually say to disarm it or the alarm will go off. and when it needs to be armed the display will say so. but..... i dont know how to program it to do so. and am really new to this. please help
I just Googled "Arduino magnetic switch sensor" and got over 619,000 hits. I think a little effort on your part and you can discover what you want.
If I could teach you C or C++ within the word count available for a post on here, I'd probably do it. But it's quite an unpractical aspiration, so I won't even attempt it.
Hopefully this will be your clue to go learn a bit of programming so we have something to build on.
Look at the examples that come with the Arduino IDE. You will probably find examples for each piece of your project.

Don't bother looking for this thread's twin; I deleted it.
thank you those of you that actually gave me advice that will help.
You're welcome
