Blink the LED on and off with 200 ms time delay using Arduino UNO board.

  AIM: a. To Blink LED On and Off with 200ms delay using Arduino.

APPARATUS: 

1. Arduino Uno Board – 1 No.

 2. LED - 1No.

 3. Resistor-100 Ohm -1 No.

 4. Bread Board – 1 No.

 5. Connecting Wires

 6. USB Cable.

CIRCUIT CONNECTIONS:

PROGRAM:

:int led = 13;

// the setup routine runs once when you press reset:

void setup() {

 // initialize the digital pin as an output.

 pinMode(led, OUTPUT);

}

// the loop routine runs over and over again forever:

void loop() {

 digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)

 delay(200); // wait for a second

 digitalWrite(led, LOW); // turn the LED off by making the voltage LOW

 delay(200); // wait for a second

}
