Documented Code
Arduino Nano Code
void setup() {
// put your setup code here, to run once:
}
void loop() {
// put your main code here, to run repeatedly:
}
This code is a basic template for the Arduino Nano. The setup() function is where you initialize any settings or configurations, and the loop() function is where the main code runs repeatedly. You can add code to read the analog signal from the microphone and process it as needed.
This document provides a comprehensive overview of the circuit, including the components used, their connections, and the initial code for the Arduino Nano.
