The Blinking LED


Built a simple circuit with 1 LED and a resistor to make the LED blink. For a bit of fun I plaid with blinking speeds - blinking evenly, on longer, off longer, etc. Quite straightforward.






1 red LED

1 red,red,brown,gold resistor (220 ohm?)

Arduino Code

/* Blinking LED
* ------------
* turns on and off a light emitting diode(LED) connected to a digital
* pin, in intervals of 2 seconds. Ideally we use pin 13 on the Arduino
* board because it has a resistor attached to it, needing only an LED

* Created 1 June 2005
* copyleft 2005 DojoDave <>
* based on an orginal by H. Barragan for the Wiring i/o board

int ledPin = 7; // LED connected to digital pin 13

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

void loop()
digitalWrite(ledPin, HIGH); // sets the LED on
delay(400); // waits for a second
digitalWrite(ledPin, LOW); // sets the LED off
delay(1000); // waits for a second


thanks for getting this up!
