Description

We hooked up the LED and a resistor to the Arduino processor and uploaded code to it that made the LED blink

Components Used

  • Light Emitting Diode (LED)
  • Resistor

 

/*
 * Blink
 *
 * The basic Arduino example.  Turns on an LED on for one second,
 * then off for one second, and so on...  We use pin 13 because,
 * depending on your Arduino board, it has either a built-in LED
 * or a built-in resistor so that you need only an LED.

int ledPin = 13;                // LED connected to digital pin 13
void setup()                    // run once, when the sketch starts
{
  pinMode(ledPin, OUTPUT);      // sets the digital pin as output
}
void loop()                     // run over and over again
{
  digitalWrite(ledPin, HIGH);   // sets the LED on
  delay(100);                  // waits for a second
  digitalWrite(ledPin, LOW);    // sets the LED off
  delay(100);                  // waits for a second
}
