I am attempting to create a led circuit comprised of 3 different series of leds. I want the circuit to power on series 1 leds for 5 seconds then power off and series 2 powers on for 5 seconds then powers off then series 3 powers on for 5 seconds then turn off then series 1 2 3 come on for 5 seconds. I'm not really sure where to start with this. I was thinking time delay relays then 555 timer(s) or capacitor and resistor. not quite sure on how to attack it. Would love some ideas or examples of how this would work.
