Blinking an LED using Arduino

Project 1

Setting Up your LED on the Arduino Board

Components

• 1 Arduino
• 1 LED
• 1 220 ohm resistor (red, red, brown)
• 1 piece of data wire

LED setup on the Arduino Board

Codes to use on the Arduino IDE

  /*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.

  This example code is in the public domain.
 */

// Pin 13 has an LED connected on most Arduino boards.

int led = 13;
int blinkTime = 1000;

// 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() {
blinkMe();
}
//blinkme function

void blinkMe()
{
  digitalWrite(led, HIGH);
  delay(blinkTime);
  digitalWrite(led, LOW);
  delay(blinkTime);
}
