Job description
An arduino project for measuring and analyzing the noise that prevails in a closed room in real time with representation on a site hosted on an arduino with a wifi module (connected to a network with internet access). The physical layout exists and is calibrated. What is needed is to complete the code with frequency analysis of noise using FFT, sharing the data on the web interface (actual and current readings), for this the site is to show two characteristics one as the volume level, that is, the history over a certain time interval (daily), where the values will be averaged for a certain time, and the second characteristic which is an amplitude spectrum in the form of a heat map, that is, the so-called spectrogram (frequency from time). I will provide detailed guidelines and likely solution paths in a private message to interested parties.
