This circuit uses digital circuits such as a demultiplexer and a binary counter to create patterns of “moving” led lights. This basic circuit is really cool when used in the dark or to light up a sign of some sort, as it creates a cool pattern that catches the eye.
One adaptation to use is to connect the most significant bit of the counter to another series of leds, enabling or disabling one of them so that the pattern will follow 16 leds instead of the only 8 shown here.
