I’m still working on my project for my simulator.
One of the projects will in principle be a separate project.
I want to create a dimmer that allows me to match the brightness of different types of lighting in terms of hardware. (Light bulbs and LEDs)
At present I can basically do this with an Arduino UNO, some code and N-Drive Shield:
I can then with different code I have received and barely understand myself combine different inputs and outputs.
For example, I can run a potentiometer that controls 3 outputs with different types of lighting. For example a 12 V led together with a 5V Led and a 5V light bulbs.
This is the first attempt I made with UNO and NDrive:
(Not my music in the background)
Why I want to be able to do this:
Because all manufacturers of different products have different LEDs and different voltages. If you also manage to get hold of a real aircraft part, the backlight in text on panels is usually 5V with tiny light bulbs. If I only connect this to a standard 5 V China PWM dimmer, of course the curve does not match each other.
Yes, but why not just use what works? Because it does not work optimally, and I do not want to be dependent on code. I want to solve this with hardware. Chip that has a non-linear curve.
So I want to be able to:
Combine different voltages.
various lighting led, light bulbs
choose which potentiometer is to control different outputs.
MATCH THE BRIGHTNESS
Then I also have a question what they mean by: PWM Control / DC Control)
What do you think they mean by DC control of backlight?
What is on the market now then:

This is someone who modifies a product from FDS
But I want to make a PCB dimmer that is much more advanced than these.
For example, is there a ready-made PWM circuit that can be controlled with a potentiometer?
Is there a circuit that is adapted to control the LED? (led curve)
I also want to be able to control the maximum of light with trim pot.
Do not know if you understand what I want to do?
In addition, my knowledge of components and chips is limited.
Thanks in advance for help!
The goal is:
MATCH THE BRIGHTNESS
