Скачать или смотреть Blink a LED bulb using an Arduino

The simplest thing you can do with an Arduino to see physical output: it blinks the LED.

@@Hardware Required
*Arduino Board
*LED
*220 ohm resistor
*Few jumper wires

//Code//
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
