that is the purpose of the 10k resistor correct?

What I would like to ask do you know how I would make a battery operated loud siren to connect to contacts on outbuilding doors of my farm so that I would be alerted with the loud extra loud siren when someone broken or opened a door. Just a simple magnetic contact switch connected to a siren and a battery that would go off when the door was open no one seems to know without going into a big rigmarole putting boxes together in all this other stuff that I don’t really need I need about five of them and so do other people on my farm area they would really like this we discussed it but nobody has the technology or know how and when we contact alarm companies they want to sell us these big complicated things that require electricity don’t need it hooked to Wi-Fi I don’t need it hooked to phone systems just loud just asking
I’m a little bit savvy when it comes to putting things together but every thing that I’ve looked up gets way too complicated for the simple situation. Many many thanks if you get this an answer me
Lynn

Hi.
You should be able to do it with just one Arduino.

Can this be done using only 1 Arduino, or do I really need 1 Arduino for each door?
I want the system to show a GREEN light when door is open, and RED light when door is closed.

Hi.
The reed switch is like a button.
So, you can use a debounce sketch.
In your Arduino IDE, you can go to File > Examples > Digital > Debounce, or you can chose the StateChangeDetection example.
Then, you just need to make a few modifications to assign the right pins.

Sara

Hi.
That refers to the pin that is connected to the reed switch. In this case it is connected to pin 6.

I have another question. It is possible to show only one message?
So ‘door is open’ 1 time and not every second? And then when I close it, once ‘Door is closed’?
