/*BlinkTurns 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 ZEROit is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set tothe 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 Arduinomodel, check the Technical Specs of your board at:https://www.arduino.cc/en/Main/Productsmodified 8 May 2014by Scott Fitzgeraldmodified 2 Sep 2016by Arturo Guadalupimodified 8 Sep 2016by Colby NewmanThis example code is in the public domain.http://www.arduino.cc/en/Tutorial/Blink*/// the setup function runs once when you press reset or power the boardvoidsetup(){// initialize digital pin LED_BUILTIN as an output.pinMode(LED_BUILTIN,OUTPUT);}// the loop function runs over and over again forevervoidloop(){digitalWrite(LED_BUILTIN,HIGH);// turn the LED on (HIGH is the voltage level)delay(1000);// wait for a seconddigitalWrite(LED_BUILTIN,LOW);// turn the LED off by making the voltage LOWdelay(1000);// wait for a second}
