How can i control a 19v LED panel wirelessly trough a Arduino Nano and what about the circuit and which electronics do i need?

Hello guys,

I'm a 18yo (Electrical Engineer) student from the Netherlands, so i'm sorry if my english isn't that good :)
So, i got a little job to do for school... i need to control a Studio Light (which is powered by a 19v adaptor) with a Arduino Nano... and maybe even with a BT/WiFi module hooked up to it for ''wireless control''. The goal is that the brughtness of the LED panel is defined by the amount of ''daylight'' that comes in trough a connected LDR or Ambilight module...
Here's a link to the studio light i'm using: https://www.amazon.com/Linkstar-LEP-1012C-3000k-5600K-Lights-Camera/dp/B06XPCXQ67

The point is, i'm new in this whole world of Arduino and programming and stuff like that... So i don't know really much about it...
I know how to build circuits and how to solder, but i definitly could use some help with the circuit diagram and maybe (a part of) the programming code :)

The Studio Light is controlled by a 10K Ohm Potentiometer and i measured 8V maximum on it... (Arduino works on 5v tho...)
I already did some reasearch online and figured out that i need to connect the middle pin (signal pin?) from the 10K potentiometer to the A0 of the Nano if i'm right?

What i did for now is that i soldered the 3 terminals of the 10K potmeter to the 3 right terminals of a DIGITAL 10K potmeter module because all i want in the end is that the brightness of the LED panel is controlled by the amount of light that comes in the LDR/Ambilight module...

So now is the question:
What is the best option for my project? Which electronics do i have to use? and what about the circuit and the programming code?
I don't have any pictures right now at the moment, but i hope to make them really soon in case you need them ;)

If something's not clear, let me know!!
Any help would be appreciated :)

Thanks!

Do not connect anything to Arduino which can output more voltage than Arduino operating voltage is (Arduino Nano operates at 5V).
I don't know what digital potentiometer chip you exactly use but they are usually controlled by serial interface (SPI or I2C), not analog signals. You better provide schematics and component names you want to use.

Start by defining this project- draw a block diagram, then start defining the details of each block.
people here can guide you along - but start by posting your first cut.

That pot might just be controlling a 555 timer wired as a PWM dimmer. Arduinos have output pins which can do PWM, I've heard. Can you post detailed pictures of the circuit board?
