What are ADC Arduino processes

Switch dimming processes for LED panels via Arduino?

michael_x:

But I just remember what a low-pass filter and a transistor are ...

Then you can bring the knowledge to life through practical experience.

You need (any) NPN transistor, which is controlled by the 0 / 5V PWM from your Arduino (don't forget the base resistor) and switches a voltage (9 ... 12 V) to the dimming input of your power supply units. Often, instead of a smoothed voltage, they can also handle a PWM signal directly, otherwise “low pass” is the keyword here.

that's exactly what I already mentioned above, that would be the easiest option if I knew how to do it?
a transistor, a base resistor?
But how do I know which one to use for this? = (

michael_x:
Do you want to dim your 6 power supplies (?!) Independently, or all of them equally?

I will write down the exact planning here again, including suggestions, etc., as I said, I am a newcomer
My current position:

I have
12 LED panels (square) each with 16 power LEDs (3.2 volts, 1 watt and 350 mA) w
Two of these panels are each supplied by a power supply unit, since the power supply unit, according to the datasheet, delivers 40 watts to 110 volts.
Does this mean that I can't put more than 2 panels on the power supply anyway?
so far is the thought correct?

According to my father, there were no stronger power supplies.

Theoretically the basic idea would be: At time X a sunrise (ALL LEDs slowly go up to full strength) should be switched over a period Xa (morning), at time Y a sunset (ALL LEDs slowly go out) should be switched over a period Yb.
But that's the basic idea, theoretically it would also be a nice gimmick, e.g. to simulate something like thunderstorms later. (E.g. control all 6 power supplies differently to cause a kind of "random flickering" of the LED panels, etc. pp)
So it would make more sense to go to each one individually, right?

michael_x:

a Real Time Clock component is a module that can be purchased, I assume?

Yes. Is there e.g. for [1 [...] technology. (A DS3231 with 2 ppm should only go wrong a maximum of a few seconds per month)

I have linked the RTC module above, should it fulfill its purpose?
Again, how do I read the time from the module? or how do I get the correct time out first? ^^ ’

VIERcntHOLZ needs one (or 6) 0 to 10V analog outputs. The board makes 5 analog inputs.
Greetings Uwe

If I see that correctly, the power supply units are even delivered with a potentiometer, in other words, theoretically I could connect this to the control cable and use it to dim the LEDs.
The Arduino should take over this process.
Do I still need a PWM signal?
Or is there already a circuit in the power supply unit that does this?
Because I can't imagine that if you could regulate this with a potentiometer, a PWM voltage can necessarily come from the potentiometer?

As a reminder, here again the data of the power supply units: Click!] (Http://www.ebay.com/itm/I2C-RTC-DS1307-AT24C32-Real-Time-Clock-Module-for-Arduino-Uno-AVR- ARM-PIC-XA- / 221550651832)
