This circuit was simple and I had no issues building it. Instead of using the blink example code, I used the morse code program that I wrote for assignment 0. The morse code program makes the LED blink my name (Adam) in morse code. The program looks like this:

# define LED_PIN 13 // Pin number attached to LED.

void setup() {
 // put your setup code here, to run once:
 pinMode(LED_PIN, OUTPUT); // Configure pin 13 to be a digital output.
}

void loop() {
 // put your main code here, to run repeatedly:
 letterA();
 longSpace();
 letterD();
 longSpace();
 letterA();
 longSpace();
 letterM();
 longerSpace();
}

void letterA(){
 dit();
 space();
 dah();
}

void letterD(){
 dah();
 space();
 dit();
 space();
 dit();
}

void letterM(){
 dah();
 space();
 dah();
}

void dit(){
 digitalWrite(LED_PIN, HIGH); // Turn on the LED.
 delay(100); // Wait 0.1 seconds (100 milliseconds).
}

void dah(){
 digitalWrite(LED_PIN, HIGH); // Turn on the LED.
 delay(300); // Wait 0.3 seconds (300 milliseconds).
}

void space(){
 digitalWrite(LED_PIN, LOW); // Turn off the LED.
 delay(100); // Wait 0.1 seconds.
}

void longSpace(){
 digitalWrite(LED_PIN, LOW); // Turn off the LED.
 delay(300); // Wait 0.3 seconds.
}

void longerSpace(){
 digitalWrite(LED_PIN, LOW); // Turn off the LED.
 delay(700); // Wait 0.7 seconds.
}
