can run at the same time without being interrupted by the LED code.

The circuit:
* LED attached from pin 13 to ground.
* Note: on most Arduinos, there is already an LED on the board
that's attached to pin 13, so no hardware is needed for this example.
* Use the onboard LED.
* Note: 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 https://www.arduino.cc/en/Main/Products

// constants won't change. Used here to set a pin number :
const int ledPin = 13; // the number of the LED pin
const int ledPin = LED_BUILTIN;// the number of the LED pin

// Variables will change :
int ledState = LOW; // ledState used to set the LED
