LEDs Sequential Turn Light AUDI Style
I present a circuit with LED game for beginners, it is made with NE555 and 74hc164; components very easy to obtain. The circuit can be powered by 6-9V; the leds light up one by one from 1 to 8 and then turn off one by one from 1 to 8, it is not a circuit in which only one lighted LED goes on. I opted for arranging the LEDs in a circle, that`s why the pcb maybe is a little bit larger, it would have been easier if I placed them in a line but this is my choice.
P.S. I am not the original author of this circuit, I just draw it.
Enjoy it!
