Smooth ignition of LEDs
Today I am listening to you, I want to present a simple scheme that has no serious practical application, but rather created to please the human eye. The purpose of this circuit is that it ignites the LEDs quite smoothly and slowly, with no threshold jumps as, for example, on Chinese Christmas tree garlands or when using a microcontroller. In fact, here is the diagram itself:
It is assembled from very affordable parts that can be pulled out of old Soviet equipment or, like me, bought. All the parts cost me 18 rubles. I used an smd resistor to reduce the bulk of soldering.
I used this circuit to illuminate the system unit with an LED strip powered by 12V; I took the same 12V from the fan connector on the motherboard. By increasing the capacitance of the capacitor you can increase the “ignition” time LEDs, you can also experiment with the resistance value.
