Turn on LEDs one after another?
I want to make a circuit where I can connect 5-10 LEDs. When I turn it on first LED should turn on for a moment and then turn off, after that the next LED does the same and so on. So that it has an appearance of 'flowing light' throughout the circuit.
The problem is that I don't know the name of this circuit or anything so I am unable to search anything on the internet regarding it. Any help would be much appreciated.
