To make some fun in a snowing night, I built a simple audio reactive LED that can dance(blink) with the music.
It’s an easy project for killing time since the circuit just contains a couple of electronic components.
I am not a professional electronic engineer. I cannot guarantee it won’t burn down your house if you run that circuit all night long.
I bet you will get much more fun if you dance with real humans rather than the LED circuit!
