By the way, please be sure to check the updated labs page since I just pushed some changes that @Mjrovai made recently.

Thanks for your comment. By mistake, the loop() portion of the code is missing (just after setup()):

void loop() {
  // read a sample
  int sample = I2S.read();

  if (sample && sample != -1 && sample != 1) {
    Serial.println(sample);
  }
}
@Mjrovai commented on GitHub (Aug 22, 2025): Thanks for your comment. By mistake, the **loop()** portion of the code is missing (just after **setup()**): ``` void loop() { // read a sample int sample = I2S.read(); if (sample && sample != -1 && sample != 1) { Serial.println(sample); } } ```
