LED Blink

Project Members: 
Laura Greig


Use the Arduino to make an LED blink.


• Red LED

• 220 Ohm resistor 


* Code found in the Arduino tutorial:

int ledPin = 12; // LED connected to digital pin 12

void setup()
pinMode(ledPin, OUTPUT); // sets the digital pin as output

void loop()
digitalWrite(ledPin, HIGH); // sets the LED on
delay(random(100,1000)); // waits for a random duration
digitalWrite(ledPin, LOW); // sets the LED off
delay(random(100,1000)); // waits for a random duration


Having image posting problems, so please find here: link



nice job, laura!

Please check with us on getting photos uploaded on the website during lab. However, flickr does add quite an experience to navigating your circuit :)
