Code (C++)

void setup() {
pinMode(13, OUTPUT);
}

void loop() {
digitalWrite(13, HIGH);
delay(1000);
digitalWrite(13, LOW);
delay(1000);
} 

Code

void setup() {
  Serial.begin(115200);
}
void loop() {
  Serial.println("test");
} 

• When the problem occurs, restarting VS doesn't help. 
• When the problem occurs, the serial output stops AND the LEDs stop flashing - so the program just isn't running.
• When it has occurred, removing the Serial commands and reloading makes the LEDS flash again.
• Restarting Windows makes everything work again (for a while).
• Sometimes I get "VMDPR_" appearing in the output window, but I think that was only when there were no serial commands.
• I can't make the serial output work at all on my laptop now; it did work once however.

Code

void setup() {
    Serial.begin(115200);
    pinMode(13, OUTPUT);
}

void loop() {
	Serial.println("led on");
	digitalWrite(13, HIGH);
	delay(1000);
	Serial.println("off");
	digitalWrite(13, LOW);
	delay(1000);
}
