Tried to send value from accelerometer to my firebase RTDB but all x y z values are 0

[slashplusdash]

If I try to test only the accelerometer, the x y z values are not 0

void loop() { // Read accelerometer values xaxis = analogRead(xPin); yaxis = analogRead(yPin); zaxis = analogRead(zPin);

// Print accelerometer values for debugging Serial.println("X-Axis: " + String(xaxis)); Serial.println("Y-Axis: " + String(yaxis)); Serial.println("Z-Axis: " + String(zaxis));

// Check Firebase readiness and send data if (Firebase.ready() && signupOK && (millis() - sendDataPrevMillis > 1000 || sendDataPrevMillis == 0)) { sendDataPrevMillis = millis();

if (Firebase.RTDB.setInt(&fbdo, "test/x", xaxis)) {
  Serial.println("PASSED: x-axis sent to Firebase");
} else {
  Serial.println("FAILED to send x-axis to Firebase");
  Serial.println("REASON: " + fbdo.errorReason());
}

if (Firebase.RTDB.setInt(&fbdo, "test/y", yaxis)) {
  Serial.println("PASSED: y-axis sent to Firebase");
} else {
  Serial.println("FAILED to send y-axis to Firebase");
  Serial.println("REASON: " + fbdo.errorReason());
}

if (Firebase.RTDB.setInt(&fbdo, "test/z", zaxis)) {
  Serial.println("PASSED: z-axis sent to Firebase");
} else {
  Serial.println("FAILED to send z-axis to Firebase");
  Serial.println("REASON: " + fbdo.errorReason());
}

}

delay(1000); // Add a delay to avoid overwhelming Firebase with requests }

Because all values are zero.

ADC2 pins cannot be used if WIFI was used.

Thanks and I read all the documentation, does it mean that all ADC2 GPIO pins are disabled and cannot be used?

You should read the blog that I share.
