I am new in this field of Arduino and my knowledge just a little electronica, I believe that the program gives me something better and am slowly doing some other things.
I have a question, aver if you can guide me a bit.
I have an Arduino UNO board, and I want to regulate a DC voltage across one of the output (PWM) Arduino. My problem is that this regulation from 0 to 5 volts.
Is there any possibility of regulating through one of the outputs (PWM) from 0 to 10 volts?
And if possible with a feeding plate 9 volts?

No it does not... It switches between 0v and 5V, nothing in between... After a RC-filter you can have 0-5V.

RC-filter it to get 0-5V and feed it to an opamp with gain 2.

Feeding plate? Is it dinner time already? Do you mean supply voltage? If you just have 9V and want 10V you first have to fix that. It's a different problem at all. But I would use a DC-DC boost converter.
But all in all, XY-problem. What are you planning on driving?
What you are referring to is NOT called REGULATION.
It is called DIGITAL to ANALOG output, which requires a DAC.
The arduino UNO does NOT have a DAC, but you can get one for $5
You need to research DACS and their associated parameters, (such as RESOLUTION)
I just wanted to be able to regulate (control) from an output (PWM) of the Arduino UNO
from 0 to 10 volts, with analogWrite (pin9, 0/255); = 0/10 volts.
Aarg ... thanks and I saw a link to the page, I'll see if I prepare the circuit and test it,
I will tell aver that such .... Thanks.

This makes me think that you don't fuly understand what PWM is.
It is NOT a voltage.
It's a digital signal that constantly switches between ground and the MCU supply (5volt for the Uno).
You can however smooth it into a constant voltage with a resistor and a capacitor.
Question is what you want to do with the signal.
Maybe your "device" is happy with straight PWM.
That only requires two resistors and a transistor.
But maybe your "device" needs a smooth voltage.
Then you need an RC filter and an opamp.
Tell us what you want to control.
Leo..
That's a vacuum tube term. I don't think there is any vacuum tubes in this post but it could be a backward obsolete electronics term from a 3rd world country.
