ok even when i press the code button </> it keeps saying it is over the 9000 character limit im not sure why. >:(
i will redraw that better for you now.
there will be a total = 30 LED strips each 15cm long each with 18 LED's
LED Strip
I have wired the system Just like a regular multiplex display, using 4 separate 7 segment displays. BUT now instead of an LED i have replaced that with a transistor that is supposed to set of a 24V LED strip.
hope that makes sense.
that is the first half of the code
