MPU 6050, Arduino Code Question!

[hobinn]

Hello!
I want it to work smoothly every second without blinking.
PLease help!

The link below is the video of using Arduino.

Your code does what you have coded

  if (voltage < 3.6) {
    analogWrite(rgbLedPin, 26);
    analogWrite(RED, LOW);
    analogWrite(GREEN, LOW);
    analogWrite(BLUE, LOW);
    digitalWrite(whiteLedPin, LOW);
    Serial.println("Low battery voltage");
  } 
  else {
    analogWrite(rgbLedPin, 255);
    Serial.println("Normal battery voltage");
  }

if this is not causing the flashing you will have to describe very precise which IO-pin switches what

Just dropping the code and an external video is not enough information

best regards Stefan
