Mistakes I've Made Building a Music Reactive LED Matrix

I love reading articles like this where you cover the mistakes along the way. Not enough people recognize the value of sharing in struggles rather than just triumphs.

It's the same reason I like watching "Nailed It" with my daughter. You learn so much more about why each ingredient is important than you would by watching someone faithfully follow a recipe with typical results.

This comes with code for an Android app, ESP32 and it that seems to work, with those lovely mistakes and solutions this is really an impressive project. I've fried buck converter trying that same solution, so be warned you always want the brightess tool in the shed.
