Sound detection with FC04

Other Hardware Sensors
1

Hi people,
ı am working on a new project with sound detection but I have a little problem.
I can not get analog values apart from 25 or 1023.
The sound sensor FC04 delıvers just 25 or 1023 in serial port.
I want to get the values between them so that I can light different colors of leds for different values. e.g: 0-150 yellow led, 150 - 500 red led, 500 - 1023 blue led etc...
Thanks ın advance for your answers.
Bye:)

You have not supplied a link to the device your talking about but the only one I can find that matches your description (here) seems to have a digital only output from an on chip comparator with an adjustable resistor threshold so you will only get high/low and nothing in between.

Hi Riva,
thanks for your reply.
I use an arduino mega 2560 r3 and as sound sensor fc04. (what you sent me per link)
You know a better one, with that I can get specific frequency?

Thanks...

This or this (almost identical) give you both digital (like the FC04) and analogue outputs.
FYI the way you describe setting it up will not display frequency but volume on the LED's. To do frequency I would suggest something like the MSGEQ7 (demo)
