How can I duplicate the 5V and GND pins on the Arduino nano board?

I am sorry, but it is manifestly clear you do not know what you are doing at all. :astonished:

The second problem is that instead of responding to answers and providing all the necessary information to guide you, you have mindlessly repeated your original question.

This attitude will entirely prevent you from getting anywhere. Telling me to "get lost" merely makes you look the more foolish. :roll_eyes:
