Điều khiển led sáng tắt Arduino

Blink
Turns on 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 takes care
of use the correct LED pin whatever is the board 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 />This example code is in the public domain.
