Hello all,

Why arduino nano always delaying 5 second before start any project ?

Thanks.

For the bootloader to time out.

Yes, remove the bootloader by writting your code with a programmer.

All this is covered on GOOGLE searches (I assume you DID search GOOGLE before asking the first question)

You can also try replacing the bootloader with the current nano bootloader (assuming you now have the "old bootloader"). The current bootloader only has the delay on reset, not on power-up.

Thanks to all of you, I already have some days ago searching in google about it but I still can't programming arduino nano via ICSP , I don't know why,  
I go step by step to burn boot loader in arduino uino and I think it's burned Ok, but I still can't use it to programming nano via ISP
