const int micPin = A0; // Microphone pin
const int leftChanPin = 2; // Left channel audio output pin
const int rightChanPin = 3; // Right channel audio output pinvoid setup() {
pinMode(micPin, INPUT);
pinMode(leftChanPin, OUTPUT);
pinMode(rightChanPin, OUTPUT);
}void loop() {
int micValue = analogRead(micPin);
int leftValue = map(micValue, 0, 1023, 0, 255);
int rightValue = leftValue; // Mono audio, duplicate left channel to right channelanalogWrite(leftChanPin, leftValue);
analogWrite(rightChanPin, rightValue);
delay(1);
}
```### Example 2: Audio Amplification with I2S Encoded Audio using ESP32In this example, we will use the Digital Power Amplifier Board with an ESP32 board to amplify an I2S encoded audio signal from a codec.```c++
#include <WiFi.h>
#include <I2S.h>#define I2S_CLK 22 // I2S clock pin
#define I2S_WS 23 // I2S word select pin
#define I2S_SD 24 // I2S serial data pin
#define AMP_LEFT 25 // Left channel audio output pin
#define AMP_RIGHT 26 // Right channel audio output pinvoid setup() {
I2S.begin(I2S_CLK, I2S_WS, I2S_SD);
pinMode(AMP_LEFT, OUTPUT);
pinMode(AMP_RIGHT, OUTPUT);
}void loop() {
int16_t leftSample, rightSample;
I2S.read(leftSample, rightSample);// Scale I2S samples to 0-255 range for amplifier
leftSample = map(leftSample, -32768, 32767, 0, 255);
rightSample = map(rightSample, -32768, 32767, 0, 255);analogWrite(AMP_LEFT, leftSample);
