Blink Assignment1

I am so excited to work with arduino for the first time. I changed around the blink interval and duration. I had no idea about how the breadboard works at first, so I just imitated the picture shown as a sample. As I connect the cables, I learned how it works on hands with a lot of fun.

 

Components Used

 

1- Arduino Uno

1- 220 Ω Resistor

1- Breadboard

1- Green LED

1- USB power cable

Code

I just changed the time intervals on the sample code.

 

 

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(1000);               // wait for a second

  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW

  delay(2000);               // wait for a second

}
