Does anyone have or know where to get a schematic(s) of a circuit to sync. LEDs to the rhythm of music? Preferrably using a 9V battery.

Or what would be cool is to have the LEDS change colors based on the frequency ranges of the music. In other words light up specific color LEDS based on the frequency of the music.

Thanks,
Joe C.

 

Hi Mech3d,

I'm new to this forum too, but I'm in the middle of a very similar project. I'm trying to build a jumpsuit that I can wear that will light up in response to the noise around me. Here the link to my thread:

http://forum.allaboutcircuits.com/showthread.php?t=42538

One of the first suggestions that I received was from a member named Bertus. He gave me this schematic:



It is beyond my capabilities at the moment; however, I'll bet that it works if you've got the know-how to build it.

There are also a few other helpful suggestions in the thread. You should take a look.

Having different color lights shine for different frequencies sounds remarkably similar to something called a "color organ."

Here's a link that might be of interest:

Unfortunately, I'm not particularly knowledgeable about electronics and circuits yet, but hopefully this will be of some help. I'll be following your thread with interest.

Good luck.

 

Then there is this one...

I haven't built it yet, but I think it will work.

I also have a not quite ready version of my LEDs, 555s, Flashers, and Light Chasers (blog, current edition) in the form of LEDs, 555s, Flashers, and Light Chasers (forum edition) that attempts to cover these issues.

 

Here is a Color Organ that I found and might try it.

 

To me it looks like the 2SA1175's are shown upside down. Normally PNP emitters go to + side??

 

About half of the circuits shown on the internet do not work!
Just the ones that I have fixed work properly.

I swear this is soo true.

How bright?
If you want it to be very bright in the daylight and there is lots of noise then you might need a wagon to carry the battery.
