Arduino program to connect a LED through push button by using the if else statement

O Level Iot Practical Assignment

Arduino program to connect a LED through push button and use the if else statement -

========================

int buttonState = 0;

void setup()

{

  pinMode(2, INPUT);

  pinMode(LED_BUILTIN, OUTPUT);

}

void loop()

{

  // read the state of the pushbutton value

  buttonState = digitalRead(2);

  // check if pushbutton is pressed.  if it is, the

  // buttonState is HIGH

  if (buttonState == HIGH) {

    // turn LED on

    digitalWrite(LED_BUILTIN, HIGH);

  } else {

    // turn LED off

    digitalWrite(LED_BUILTIN, LOW);

  }

  delay(10); // Delay a little bit to improve simulation performance

}
