Lab 1: Blinking LED

Description
The lab is an introduction to Arduino and physical computing. The Arduino microcontroller was connected to a laptop to make an LED blink. I used the sample code provided and changed the "delay()" value to 500 to ensure that the code is working properly.
 
Components

• 1x 220 Ohm Resistor
• 1x Green LED
• 3x Jumpers
• 1x Arduino Uno
• 1x Breadboard

• 1x Macbook Pro

 
Code

  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.

// give it a name:

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(500);               // wait for a second

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

  delay(500);               // wait for a second

}
