Hi, I need to control 25 led's, one after another. Everything is fine with 2x 595 and 16 leds, but I don't know how to add another 3x 595 and rest of led's :~ When I add third 595 it light up all led's connected to it after last led in second 595. /* Created 23 Mar 2010 by Tom Igoe */ //Pin…

how to drive 25 led with 5 pcs of 595 shift register?

I'd select quite a low clock frequency in the first instance

how to do that?
