Code: Select all

void setup() {
  Serial.begin(460800);
}

void loop() {
  delay(3000);
  Serial.println("Hello!");
}

The problem is that I can't make the serial monitor to show "Hello". The result is always just unreadable symbols.
I have tried to play with bauds without any success.

Could you help me?

The upload speed is not the same as the serial speed when the program is running. Try 'Serial.begin(115200);' or even just 'Serial.begin()' instead.
