hello.

i am new to arduino and i want to set up 3 alarms...

below is the code i found on the web... i tried to understand it but in vain...

can you guys help me...

Sure.

First piece of advise is to put your code between code tags like you were instructed to do in the stickies at the top of this forum that you read. You did read them, right?

Second, tell us exactly what your problem is. What have you tried? What didn't work the way you thought it would?

As someone new to Arduino, and maybe computer languages in general, you would have problems understanding it.

If its your first Arduino project, start with a program that is a great deal simpler, such as the blink sketch, modify it, make the changes work etc.

In addition if you have problems with a program do appreciate that forum members dont know what those problems are unless you actually tell us.

To post code and/or error messages:

Use CTRL-T in the Arduino IDE to autoformat your complete code.
Paste the complete autoformatted code between code tags (the </> button)
so that we can easily see and deal with your code.
Paste the complete error message between code tags (the </> button)
so that we can easily see and deal with your messages.
If you already posted without code tags, you may add the code tags by
editing your post. Do not change your existing posts in any other way.
You may make additional posts as needed.
Please provide links to any libraries that are used
(look for statements in your code that look like #include ). Many libraries
are named the same but have different contents.

Before posting again, you should read the three locked topics at the top of the Programming Questions forum, and any links to which these posts point.

If your project involves wiring, please provide a schematic and/or a wiring diagram and/or a clear photograph of the wiring.

Good Luck!
