hi i need some help. im in a jr. high class where we build and code things, there is a project i wanted to do be it is complicated, i was wondering if any body knows how to sync LED's to a speaker so the lights will flash to the song thats playing.

What have you tried, so far? Have you done any online research?

"Arduino color organ" might be one useful search term.


“Sound to light”, “ disco light project” are worth searching too.

Lots of people here know how to do it , probably designed by researching what’s needed , then writing some code - They learnt a lot by doing it too. I’m sure we want that for you as well .

Good luck , post some code when you’ve a specific issue
