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 https://www.arduino.cc/en/Main/Products

This example code is in the public domain

// the setup function runs once when you press reset or power the boardvoid setup()

digitalWrite(10, LOW); // turn the LED off by making the voltage LOW digitalWrite(11, LOW); // turn the LED off by making the voltage LOW digitalWrite(12, LOW); // turn the LED off by making the voltage LOW digitalWrite(13, LOW); // turn the LED off by making the voltage LOW delay(MyDelay); // wait for a second
