// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A3);
// print out the value you read:
Serial.println(sensorValue);
delay(1); // delay in between reads for stability
}

ESP32 family with native USB capability is that they are typically configured to have their USB CDC serial port disabled by default.
Luc.Paquin Replace A3 with the correct pin number based on your board’s pin mapping. For the Beetle ESP32-C6, analog pins are typically mapped directly by their numbers rather than the A0, A1, etc., convention used in some Arduino boards.You can edit your code like this:
// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin (e.g., GPIO 4, which might be the correct analog pin):
int sensorValue = analogRead(4); // Change 4 to the correct pin number
// print out the value you read:
Serial.println(sensorValue);
delay(100); // delay in between reads for stability
}
