Hi there!
First off, as a couple of other folks have noted, you will get more respect if you type as though you were taking some pride in what you wrote. I don't mean your English has to be perfect (your English is much better than my Portuguese
) but don't use cell-phone txt-speak such as 'ppl'.
Second, it's not a good idea to try to make a single thread for many different topics. A forum or newsgroup structure is designed for "one topic, one thread". Each topic (question) should have its own thread, and each thread should pertain to only one topic. It makes it far easier to see what's going on, to search for past threads later, and is just the way people expect it to work. So forming one thread in the hopes that people will post many questions to it is not a good idea.
Third, it is impossible to answer your question on the LEDs without information about how the circuit is currently set up. All we see is some LEDs blinking. For all we know, they're blinking because you have a sound sensor and the barking dogs are triggering the circuit. Post the schematic and some information about what you've tried and then maybe someone can help you out.
Anyway, I don't mean to shout you down or anything but there are just a lot of things wrong with this. Post information about your schematic if you want answers and write your posts as if you are making the same kind of effort which you would like us to spend in helping you, and you will have more luck getting answers.
Good luck,
Torben
