Two LEDs Running at Different Speeds

int ledOnePin = 13;
int ledTwoPin = 12;

void setup() {
pinMode(ledOnePin , OUTPUT);
pinMode(ledTwoPin , OUTPUT);
}

void loop() {
  initializeLed(ledOnePin , 500);
  initializeLed(ledTwoPin, 1000);
}

void initializeLed(int led, int time) {
digitalWrite(led, HIGH);
delay(time);
digitalWrite(led, LOW);
delay(time);
}

Two LEDs Running

int ledOnePin = 13;
int ledTwoPin = 12;

void setup() {
pinMode(ledOnePin , OUTPUT);
pinMode(ledTwoPin , OUTPUT);
}

void loop() {
  initializeLed(ledOnePin , 1000);
  initializeLed(ledTwoPin, 1000);
}

void initializeLed(int led, int time) {
digitalWrite(led, HIGH);
delay(time);

}

Blink LED Mostly On

int ledPin = 13;

void setup() {
pinMode(ledPin , OUTPUT);
}

void loop() {
initializeLed(ledPin, 1000, 1);
}

void initializeLed(int led, int onDelay, int offDelay) {
digitalWrite(led, HIGH);
delay(onDelay);
digitalWrite(led, LOW);
delay(offDelay);
}

Blink LED Mostly Off

int ledPin = 13;

void setup() {
pinMode(ledPin , OUTPUT);
}

void loop() {
initializeLed(ledPin, 1, 1000);
}

void initializeLed(int led, int onDelay, int offDelay) {
digitalWrite(led, HIGH);
delay(onDelay);
digitalWrite(led, LOW);
delay(offDelay);
}

The Changed Blink Program

int ledPin = 13;
void setup() {
pinMode(ledPin, OUTPUT);
}
void loop()
{
digitalWrite(ledPin, HIGH);
delay(100);
digitalWrite(ledPin, LOW);
delay(100);
}

I changed the timer so that the light will blink so fast it doesn't look like it's blinking.

The Blink program

int ledPin = 13;

void setup() {
pinMode(ledPin, OUTPUT);
}
void loop()
{
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
}

LED YouTube Video 4

This was a simple project but I thought it looked cool and could be something fun to try. He mentioned where he got the idea from and provided links to useful websites in the description.

I liked this project as it showed plenty of uses for the cube as well as advice on getting the hardware and information about each activity. I also liked it because you can use the Arduino Uno to run it.

LED YouTube Video 2

http://www.youtube.com/watch?v=cQhBm_EgB0w

This is an extremely cool project where they build a ring that spins around and has LEDs attached to it, to create certain shapes including a globe. They provide a link to more information including code and layout.

I found this video interesting as he showed what a made board is to look like and he described what he used. A good thing about this is you can talk to the author and he will send you the code if you want.
