Using FC-109 module but not getting output

[tusharvb19]

I am using this module having fixed 20dB gain i.e. 10x!!!

Can you help me to modify your code to get it work!

[amiravni]

The code stays the same, but the power to the mic should be 5 volts instead of 12 volts.

[tusharvb19]

I have connected the vcc to 5V only..but I have not connected the LPF!
Will try tomorrow with the LPF.
Is LPF is compulsory?

[amiravni]

You can try without first, might be more noisy

[tusharvb19]

Without LPF it gets continuously on and much noise!
Will try with LPF.
And I have connected IRF mosfets without registers to led strip.This can cause issue?

[amiravni]

IRF MOSFETs are fine, but what do you mean without registers? Without connecting them? So how do you know it works?

[tusharvb19]

I have already built this circuit but as i am not having MSGEQ7 I am using FC-109 amp module and will integrate your code sir. So ignore the MSGEQ7 connections and I am using IRF540N (http://www.infineon.com/dgdl/irf540n.pdf?fileId=5546d462533600a4015355e396cb199f).

Now I am using completely your circuit except the mic module! I am using FC-109.
But still I am not getting the desired output as you have shown in your video!

This is my serial monitor without music.(local noise though)

[amiravni]

It's a bit hard to debug it from here :)
Did you use the exact components values for the LPF?
Try to input a frequency sweep and then you might understand were exactly the problems are:
https://www.youtube.com/watch?v=hvkipAlRKq0

[tusharvb19]

Yes I am using the exact values and hardware except the module as FC_109( fixed 20dB/10x).
What will be the values(No filt Val) on serial monitor if I am playing frequency sweep?

[amiravni]

take a look on the filters visualization in the post:
http://www.whatimade.today/lets-make-some-signal-processing-with-an-arduino/

You should see the leds react to the sweep according to the filters

1. LPF - Should react up to around 300Hz ( probably will react a bit up to 1Khz as well)
2. BPF - Should react to frquencies 2Khz-4.5Khz (probably a bit more than that)
3. HPF - Should react to frequencies higher than 4Khz

Since they're all digital filters these are "more-or-less" the numbers. But if you see the led connected to the HPF output light with low frequencies it should point out there's a problem.

[tusharvb19]

I think due to low 20dB output it is not giving expected output.. Now the leds and No filt values varies according to frequencies and on seep test but they are not switching to off!
