Hello everyone I have not used Arduino much before.Need some help !!
I want to build a specific frequency detection system. generally capture a sound from a microphone, then do ADC, FFT analysis of the signal, then if it detects a frequency of 2.2 KHz i need to output a sound or light up an LED.
So what I want to know is if its possible to achieve the DSP processing using ATmega328p chip in arduino UNO? any similar projects anyone have done?
