You have already asked this question! Have you searched the forum as suggested in your original post?

i searched the hole day and can't find it so i ask again.

If you don't get an answer the first time you ask a question, the best approach is not to start a whole new topic with exactly the same question. You can reply to your previous topic which will bump it back up the list of topics and someone else may see it and be able to respond.

I'm locking this topic to prevent any further discussion here - please use your original topic - How to flash a LED?
