I have built a little headphone amp and going to encase it. I like to add an indicator in front of the tiny case which will indicate that music is playing on, like some sort of led VU meter 😀
Can anyone suggest me anything that will serve my purpose? I need schematic diagram of such thing if possible. Thank you all in advance.

Hi,
Look for LM3915, LM3916. Very useful ICs for this.
In the datasheet you can find some application circuits.
