Lab 1 Submission: Chrisfan

Description: The purpose of the lab was to create a simple LED blinking circuit using the Arduino. I created a simple SOS sequence corresponding to morse code. This consisted of creating a series of three short blinks ("dots") followed by a series of three longer blinks ("dashes") followed by the original three short blinkes ("dots"). 

• Components Used:

1.    Breadboard

•    Arudino Uno
•    1 220 Ohm Resistor
•    3 wires
•    USB Power-source
•    Red LED

Code:

int led = 13;

void setup() {

  pinMode(led, OUTPUT);

}

void loop (){

  // dot dot dot blink

  digitalWrite(led, HIGH);

  delay(100); 

  digitalWrite(led, LOW);

  delay(100);     

  digitalWrite(led, HIGH);

  delay(100); 

  digitalWrite(led, LOW);

  delay(100);     

  digitalWrite(led, HIGH);

  delay(100); 

  digitalWrite(led, LOW);

  delay(100);   

  // pause

  delay(200);   

  // dash dash dash blink

  digitalWrite(led, HIGH);

  delay(500); 

  digitalWrite(led, LOW);

  delay(500);

  digitalWrite(led, HIGH);

  delay(500); 

  digitalWrite(led, LOW);

  delay(500);   

  digitalWrite(led, HIGH);

  delay(500); 

  digitalWrite(led, LOW);

  delay(500); 

   delay(200);   

  // dot dot dot blink

  digitalWrite(led, HIGH);

  delay(100); 

  digitalWrite(led, LOW);

  delay(100);     

  digitalWrite(led, HIGH);

  delay(100); 

  digitalWrite(led, LOW);

  delay(100);     

  digitalWrite(led, HIGH);

  delay(100); 

  digitalWrite(led, LOW);

  delay(100); 

  //pause

  delay(1000);
