    Hello there guys,

    I have a bit of a problem with a project for uni, sorry if this is answered on this forum and i didn't found it.

    Well, long story short, i have to make a circuit that lights up 3 led strips , with a delay of 3 seconds between them like this: the first led strip lights for 3 seconds,then shuts down, after that, the second led strip lights for 3 seconds then shuts down, and after that the last one lights for 3 seconds. After this cycle is done, it runos all over again, till the end of time (joke). I'm running a few simulations on Proteus 8 with a 555 and a few 12v light bulbs, since i haven't found any led strips on the program. The leds that i have are white, run on 12V and have 6W/M .

    So far, i managed to light two light bulbs with the required deley between them, but i have no ideea how to light the third.

    This is how my circuit looks like.

    I'm oppened to sugestions, however, i don't want to use an Arduino.

    Thanks a lot guys,

    Is this a project at university level?
