Hello
I am looking for a way to light in LED in sync with audio playing on a PC. I am aware there are kits etc that can do this but I was interested as to whether this can be done via a circuit connected to the 3.5mm audio out socket?
I came across this tutorial which is the kind of thing I am after - https://www.instructables.com/Creating-An-Audio-Reactive-LED-Circuit
I haven’t tried this yet as don’t think I have a 2N3904 transistor. So before I order one I thought best to post here to garner thoughts on the matter.
Thanks!
