hello forum i need help with this projects

I'm working on a Arduino Nano to control a 12v relay for power i wanted this keeps on for 8 min after the powers turns off and restart the cycle every time if receives the power back on if some body can help me with what code i can use for it from library

arduino uno nano
12v relay module

Your post was MOVED to its current location as it is more suitable

thanks for the correction

What do You want tell by that?

No question in Your post so I'll say thanks for telling. Go on, good luck.

if somebody can pointed me on the right direction means what code example can i use for it yea and you right my post is not clear about what i want

I get it.
Split the project in 2 parts.
Number one, doing things at certain time. Example can be "Blink without delay" found in the Arduino collection, maybe even in the IDE.
Number two, controlling a relay.
2 possibilities.
Number 1. Buy a relay module that's rated for the current and voltage it will handle.
Number 2. Use a logic level N channel MOSFET to handle a conventional relay.

i was thinking on something more simple example:
connect a 12v power converter to 5v to turn on the Nano so then give a signal to activated the 12v relay to activated the device so when i cut the 5v the relay keeps open sending the 12v for 8 min after those 8 min the relays cut the power and re start the cycle

That's not possible.
