Hi,
I am having difficulty in finding the perfect application for my car.
I noticed that Velleman do the following product
I want to place many of these together to create a spectrum analyser similar to this:

So every bar needs to work individually.
Could anybody point me in the right direction please??
This is a VU meter, not a spectrum analyser.
You require a different circuit, which unfortunately we do not carry at this time.
OK not to worry thank you very much for you help.
Make a “high pass” and a “low pass” filter and put one after the other for each channel. This will make a “band-pass” filter which will allow a range of frequencies to pass through, you can then put the output into a VU meter. Make multiple filters, one for each range of frequencies and connect them to your VU meters and that should work
