Summary

Gadget: Sound Alert System

Description: This gadget utilizes Arduino and various libraries to create a sound alert system. The main functionality of the code is to detect specific frequencies with certain intensities and display corresponding alerts on an OLED display.

The system continuously captures sound through the Max9814 microphone, performs fast Fourier transform (FFT) analysis on the sound data, and checks for specific frequencies and intensity thresholds. When a detection occurs, an alert is triggered, and the corresponding message is displayed on the OLED screen.
