Hi @welemirelkrain. When I'm having trouble with serial output, I like to do a quick check with the most simple possible sketch. If this works, then I know the problem has something to do with my real sketch. If it doesn't work, then I know the problem is not related to my sketch code. It seems maybe a little silly, but it allows me to be sure I'm focusing my troubleshooting efforts in the right direction.

Try uploading this sketch to your Arduino board:

  1. Copy and paste this code as a new sketch in Arduino IDE:
    void setup() {
  Serial.begin(9600);
}

void loop() {
  Serial.println("hello");
  delay(1000);
}
  2. Upload the sketch to your Arduino board.
  3. Select Tools > Serial Monitor from the Arduino IDE menus to open the Serial Monitor view if it is not already open.
  4. Make sure the baud rate menu at the top right corner of the Serial Monitor panel is set to "9600".

Do you now see the word "hello" being printed in the Serial Monitor's output field once a second?
