Hi, i was wanting to construct a simple circuit where a led would flash together with a Music BPM. Does anyone knows how it can be done. And what will i need to buy? OK Thanks...
How to make a LED flash together with the music BPM

Just a simple idea, so I am not sure but you'd probably need to pass the signal through a Low Pass filter since the beat is at low frequencies of the audio spectrum and then you could feed it to a BJT that controls the current passing through the LED.

Google for "color organ". These usually have 3 or more frequency bands, but you will get the idea. Just build the low band if you only want the bass beat.
