If you can't do it without asking, you really need toquestion trying to use mains electricity. Start simple and stick to LEDs

What he's saying is ...learn to make an led chaser with 555 and 4017. When you can do that you can hook up your scrs.

How many LEDS? I doubt you need the SCR at all - 555 timer, 4017 decade counter or two or three or more and if you need bright LEDS a transistor to drive a suitable LED.
