Set specific barriers for each column? #2
Description
I'm new to Arduino programming and barely understand how your program works, but I'm very much trying to replicate a similar project. I need to set barriers like column1 is 50-150hz, column2 is 151-250hz etc. And then set the rows according to the dezibels or amplitude.
For example: I have a 100hz sine wave that's loud as possible, so only column1 should light up.
Could you help me with that? I'd gladly appreciate your help
