Hello to you
from me
I started on this led welcome sign beginning of may something 2016 and finally got most of the thing done
now I just need to put it in a box and set it somewhere
anyway I used 11 74hc595 chips which i ran 3 pins for 6 and 3 pins for 5 and 2 pins to clear all on the b.X side of a 20m2
I used cat5 connections because my wires would be a pain to solder if trying to hook every together
plus I can reuse my board if I want to hook up something else
I used all sockets for my ic's just incase one freaks out its easy to change
when i built this sign I knew i was going to have headaches but luckily it was just minor solder flaws and the pc board from (china) had some copper strips touching
my code isn't nothing for perfection but I have it working
here is video of paper in front of the leds
