I am attempting to make a clock out of 4 rows of LEDs each row representing one of the digits on a clock and each LED in the row representing a numeric value that indicates the time.
I am using Arduino Uno and am fairly certain that charlieplexing is the only way that I could make it work.
This is the base code that I am using.

Is this the best charlieplexing code for my situation?
and what would be the easiest way to use the delay function for this?
This is another code that I found but haven't tested it because I am pretty new to this and have a limited knowledge of coding.
At this point any information would be helpful.
