Pins of the ATmega328p

Hello,

I am trying to find wich pin outputs 5V on the atmega328p.
I have been looking thru the datasheet but I can't find anything that informs me about it.

Ive googled some things but I am not sure. Could it be thath the AVCC pin outputs 5V or the RESET? Because (AVCC) is one of the 2 power pins and the VCC is already used to supply the µC.

And on google I found thath the RESET pin outputs 5V.

Why are you trying to find that?

Because in a school project Im using the Arduino Uno wich has the ATMega328p µC. In the scheme im using I made a pin called "5V". My teacher wants me to add the name of thath pin from the ATmega328p since it does not have a pin called "5V".
Ive been looking through the datasheet but I can't find anything really.. Its around 600 pages and ive searched for every sentence thath includes "5V" no usefull results tho.

There are no pins on the ATmega that specifically output only and exactly 5V.

The Atmega needs to have a supply voltage of between 1.8v and 5.5v, which is connected to the pins labeled as VCC.

You should study the schematic for the Uno. You can download it from the "Documentation" tab of the Uno's product page:

The Arduino Uno, which is a board based on the ATmega328p chip, of course has (a) an on board voltage regulator and (b) a USB 5 volt output (assuming it powered via a USB cable). These supply the power to the chip. Post #4 above refers you to the schematic diagram.

VCC, AVCC and RESET are all inputs.
But VCC and AVCC is where you would connect your power supply.

You should just connect your 5V output pin to the power supply.
