Introduction: LED Blinking Using Arduino
Hardware Required:
1) Arduino Uno
2)LED
3)4.7k Resistor
4) Connecting wires
5) Bread Board
Please connect the led to arduino as shown above .
Arduino 3rd pin is connect to +ve pin of LED and -ve end of LED is connect to ground through 4.7k.
Step 1: Program for LED Blinking
void setup() {
// initialize digital pin 03 as an output. //
pinMode(3, OUTPUT);
}
// the loop function runs over and over again forever
void loop()
{
digitalWrite(3, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(3, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
Copy and paste the below code in Arduino ide and upload to Arduino UNO.

Quite a bit like https://www.arduino.cc/en/Tutorial/Blink but you use a much larger resistor, any reason?
