I want to make a small digression right away, I was not going to remake the LED lamps for ready-made (sold in stores) dimmers. I decided to make myself a brightness control unit based on the ATmega128 microcontroller and control the brightness using PWM.
To begin with, I bought such LED lamps for my dacha.

Actually, the flickering and buzzing of the power boards of some lamps, this is why I decided not to buy ready-made dimmable lamps, buy an ordinary one, and do the brightness control myself. So I will have equal illumination without flicker at any brightness, there will be no buzz at all over my head, because the power supplies will be taken out to the attic. In the lamps themselves, only the LED strip remains and that's it. Well, since I do everything myself, it's easier to fix my own if something suddenly breaks.
In the next post I will write directly about the regulator and show how it works.
