How did you make the string scroll? can you please tell the command for it?
ReplyDeletenot enough temperature
ReplyDeleteGood morning,
ReplyDeletei am using 32x32 rgb led mtrix panel with arduino uno while running the example programs from arduino ide provided by the library files, the screen was splitting into 4 parts. can you suggest me to overcome this problem. while running the program which is provided you also have the same problem with arduino Mega.
Good morning,
ReplyDeleteI would like to show the Temperature for this clock, please help to teach me. Thanks!
hello
ReplyDeletethis work good.
but per 2-3 minutes one screen full clear and one second again open.
this is normal?
thank you
Can you send the full code and all libraries because I compile lot of error appearing , I am using Win10 and Arduino 1.8.13
