Homework 1

Description

Create a blinking LED

Components

LED light

Board

Resistor

Code

/*

  Blink

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

  This example code is in the public domain.

 */

void setup() {               

  // initialize the digital pin as an output.

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

  pinMode(13, OUTPUT);    

}

void loop() {

  digitalWrite(13, HIGH);   // set the LED on

  delay(1000);              // wait for a second

  digitalWrite(13, LOW);    // set the LED off

  delay(1000);              // wait for a second

}

Description

I built a single circuit using the directions on the website and picture as an aide. It was helpful for me to clarify how the board is constructed so that I can understand how the energy moves through my circuit.

I downloaded the programs and installed the correct drivers. And I was super excited when the little LED lit up. I am easy to please.

void setup() {               

  // initialize the digital pin as an output.

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

  pinMode(13, OUTPUT);    

}

void loop() {

  digitalWrite(13, HIGH);   // set the LED on

  delay(5000);              // wait for a second

  digitalWrite(13, LOW);    // set the LED off

  delay(5000);              // wait for a second

}

Description

I changed the rate of blink for the LED to 5 seconds on then 5 seconds off.
