Hello sir. I am a student from Europe. I want to work on high frequencies such as 8 kH. Is this the best module I can use. If It is not which will be best for it.

I have an Arduino UNO board. I wanted to measure frequency of a monotone wav file playing in an amplifier speaker using Python. I did not get any pyfirmata fft code to accommodate with python. Can you please let me know how i can handle this?

Hello, im working on a project that's very similar to what you're doing here. Maybe you can give me some tips or exchange ideas. My design is for automotive diagnostic use. My project has to do with a stethoscope for monitoring frequency. Being a technician I know this device already exists, but I wanted to build my own. Thanks Al

I don't see where you linked to the FFT library, so I'm assuming this one: https://github.com/kosme/arduinoFFT I had that running on an ESP8266 based WeMOS D1 Mini, but didn't know that it worked on an AVR, as I'd just been using the Open Music Labs version on my Nano's. Will try this one on the Nano as it's got a few cooler features than the Open Music Labs implementation. Otherwise, please provide a link to the FFT library you're using.

After you recognize the digital frequency signal, is there a way to convert that frequency to an LED color (example: Blue for 1015Hz)

Doctor, great work. I'm talking about Brazil and Can you help me with this doubt? How could I create a code where an LED blinks when the sound enters the frequencies of 1000Hz and 2000Hz.
