Topic: LED's to different audio frequencies? (Read 526 times) previous topic - next topic


Is it possible to split digital outputs to be able to add more LED's on them.
And is it possible to make LED's blink independently to a different audio frequency Per LED, instead of all of them blinking at the same audio frequency range.
i am very new at this so if you have any premade code this would be very useful.
i have an arduino uno R3.


It's certainly been done. Google "Arduino color organ". That's what you're looking for.

You can't "split" a digital pin. That doesn't really make any sense. But you can certainly connect more than one LED to a pin provided you want them to switch on and off together.



thats exactly what i was looking for thank you very much
