how do you even find motivation to keep posting video after video?
well originally things like youtube or whatever was more of a hobby, people would upload stuff because they felt like it and wanted to - it wasn't really get famous and rich like people hope for today.
so you have to ask yourself what your goal even is.
is it the issue on github mentioning not being able to read the switch matrix? if so, have you tried to read the io pins yourself without an additional library to see if they do as you would have expected?
