Assignment#1. Blinking LED

Project Members: 
Seung Wan Hong

Blinking LED 


After installing Arduino software and setting hardware, through LED and a register, I made blinking LED according to suggested electronic plan.



220-Ohm Register(red-red-brown-gold strip) 

Arduino Code

/* Blinking LED
* ------------
* turns on and off a light emitting diode(LED) connected to a digital 
* pin, in intervals of 2 seconds. Ideally we use pin 13 on the Arduino
* board because it has a resistor attached to it, needing only an LED

* Created 1 June 2005
* copyleft 2005 DojoDave <>
* based on an orginal by H. Barragan for the Wiring i/o board

int ledPin = 13;                 // LED connected to digital pin 13

void setup()
  pinMode(ledPin, OUTPUT);      // sets the digital pin as output

void loop()
  digitalWrite(ledPin, HIGH);   // sets the LED on
  delay(1000);                  // waits for a second
  digitalWrite(ledPin, LOW);    // sets the LED off
  delay(1000);                  // waits for a second
