Lab 1 - Blink

Description
Our first lab assignment was an introduction to Arduino and physical computing. We installed the Arduino software onto our computers and created a simple circuit to make an LED flash on and off. I modified the existing code which turns an LED on for one second and off for one second to flash on for only a tenth of a second and off for 5 seconds.
 
Components Used
1- Arduino UNO
1- breadboard
1- LED
1- 220 ohm resistor
2- colored wires
 
Code

/*This code is modified from the Blink example code to make an LED turn on for a tenth of a second and then off for five seconds, repeatedly. */

// 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(100);               // wait for a tenth of a second

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

  delay(5000);               // wait for five seconds

}
