Jan 30 2013 Lab Submission - Blink

 

A simple blink application is tested in this lab session.

A green LED turns on for 500ms in every 100ms.

Through this session, I've come to understand a basic usage of Arduino, matrix structure of the breadboard, the polarity of LED.

 

 

 

- 1 green LED

- 1 220  ohm resistor

- 1 Arduino Uno board

 

 

 

The code is based on an example 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(100);               // wait for a second

}
