Hi dear community;
i have 4 x MAX7219 Module with Arduino Uno.
i was found some scrolling text examples for MAX7219 Module on internet, then i run it without any problem but i want to make 2 change on project.
This is the code what i run without any problem;
(Thus 9000 character limit of this post i cannot paste the code here as text)
1-) i added two 10k potentiometer to breadboard and added code to IDE to adjust scroll speed and brightness.
POT's are works but problem is; when you adjust the POT, scroll speed or brightness on the MAX7219 doesnt change until next loop.
İs there a way to adjust instantly ? so i dont have to wait untill next loop of code ?
This is my POT added code later on

And this is the video of what happening
https://youtu.be/wso0ny1WRPA2-) How to add specific pattern to char list ? e.g a Heart or Smile pattern.
I simply tired to modify one of the current byte array like; #
but i could not able to use 8x8 fully because byte array in this set seems 5x8 thus i cant fit the heart and simle to limited set.

any way to do this ?
Thanks in advance, Best regards.
