Blink
Turns an LED on for one second, then off for one second, repeatedly.
Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
the correct LED pin independent of which board is used.
If you want to know what pin the on-board LED is connected to on your Arduino
model, check the Technical Specs of your board at:

// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

Other Steps to Reproduce
I have downloaded drivers and also tried different comp ports but i am unable to upload the code
I have checked existing issues, online documentation and the Troubleshooting Guide
[X] I confirm I have checked existing issues, online documentation and Troubleshooting guide.
Ensure that you're using a micro USB data cable and not just a regular charger wire. Faced the same issue, got resolved after changing the wire and rechecking the "Port" in the Toolbox dropdown.
