I actually was just reading about those IC's. Maybe I was describing the effect im looking for incorrectly. I used the word sequence which may have been incorrect. I want the leds to turn on one at a time but stay on. It looks to me like the IC turns one on then off, then the next on then off and so on. Im looking to simply light up all of the leds and have them stay on, but make it with a small 75th of a second delay from one to the next. That way all 75 will turn on in 1 second total. Does this still require an IC or is there a way to use a CAP to control the delay.
