First off, any advice or guidance would be greatly appreciated. I'm using parola and some maxx7219 modules for 8x8 led matricies. Being fairly new to arduino, I'm pretty pumped that I finally figured out how to get the text scrolling. My question is: would it be possible to be able to change the message that scrolls, without having to connect arduino to my computer every time? Maybe using a keyboard to type it into the display directly?
I use an hc-05 bluetooth module on my Arduino operated Parola display to change the settings, and/or the message displayed. No direct connection needed.

It's rather big, but with a bit of luck you may already own a use-able keyboard

So do you just use the Bluetooth module to upload your sketch to arduino?

No, my sketch is already running and completely finished. I merely connect to the Arduino via Bluetooth to change any or all of the optional settings the sketch uses like the date, time, effect transitions, day/night light trigger settings and scrolling message. Those are then written to EEPROM to save the new settings and use as defaults in the event of a reboot.

Hi again Mel,
Would it be at all possible for you to post an example of your sketch that you use for parola? I'm having trouble understanding how to communicate via Bluetooth to change the optional settings you mentioned.
