Hello All About Circuits forum,
Using an Arduino to control a dozen 4017 - 555 circuits to sequence
320 LEDs. The problem is the 4017 turns on LED 1 then turns it off
and then turns on LED 2. The project wants to turn on LED 1 and
leave it on and then turn on LED 2 and leave LED 2 on, then
turn on LED 3 etc.
Maybe the 4017 won't do this but does any one know if it will
and if so how?
Thanks.

320 outputs, post #1.I'm assuming that you want 10 digit output here.
That's not a bad price if you need 50 pieces. $0.31 each. <<< Good buy.
That's equivalent to the OR operations built with diodes. The diode approach is cheaper and more affordable, however.4017 "stacker".developed for Oxbow-Rene.
