What is Arduino Sound Meter Code Example about?

This document contains code for an Arduino sound level meter that displays decibel readings on an OLED display. It initializes the OLED display and sets the font size. It then enters a main loop where it takes samples from the microphone over a 50ms window, calculates the peak-to-peak amplitude, maps this to decibels, and displays the reading and a bar graph on the OLED. It draws a scale and outline for the bar graph before filling it proportionately based on the decibel level.
