How do I make a string of LEDs light up in sequence (one after another as if the the light is "moving")? Answered

I am trying to make it so when I press a button the LEDs would "run" up and down the strand a few times and then all blink at once (totaling about 5-10 seconds). I understand circuits and everything, would I need to get a programmable chip? I am not well versed in programming, but I guess I could try to learn. Is there a way to do this w/o an IC?

you can get any basic electronics workbook and get the chasing light circuit but as far as getting them to blink all at once you are going to need a secondary timing circuit i would use a 555 to delay until the chase sequence is done then a second 555 to introduce your pulse for all of your leds to blink at once.

I am wondering if there is something I can buy I have a old four light traffic light if I hook them all to power they all light up. Can I buy something to make them run in sequence like red Amber green and green arrow?

Simple! I use this module from "special effects magic" in all my LED projects! Tiny in size and pretty straightforward!

not easily, if it all. the easiest way would be to get a board like the arduino mega, and hook all of the lights up to pwm
