Blink without Delay
Turns onand off a light emitting diode(LED) connected to a digital pin,
without using the delay() function.This means that other code can run at the
same time without being interrupted by the LED code.
The circuit :
-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 :
