Thank you all for your time, but this started to look very difficult for me. I feel like trying to understand, I don't know, maybe rocket science, and without knowing to multiply or divide... =(
I've just started learning arduino IDE and all of it's commands, so working with libraries is really hard for me. Don't get me wrong, I really appreciate your time and effort, but simply I don't fell that currently I'm able to learn all that stuff and understand it. :blush:
I tried your sketches on your forum, and I saw that they work with some simple pattern beforehand specified. Sketches for 4 shifters and commands in serial monitor don't work for me. I used 2 shifters ( currently don't have more ) and all that happens is LED No.9 ( first on shifter No.2 ) is always On, and none of those commands work. Maybe I fu*ed something up...
I was kinda hoping that all of this could be done very easily. With For loop a get every line from *.txt file every 750mSec, with serial.available() check if there is any data on the serial port, and if so use some variable to "store" it ( maybe with serial.read() ) and send it to LEDs with shiftOut().
What happens is serial.available() gives "0" like there is no data, and I got stuck on very beginning of my idea...
Bottom line, I don't feel ready ( and I don't have the knowledge, hence NOOB in topic title ) to work with arduino on advanced level. I was hopping that all of this can be done more easily and beginners friendly. If not, all I can do now is learn as hard as I can, and try to figure something out. Every help is welcome... :roll_eyes:
