Tangible User Interfaces - Fall 2011

Description

Use the Arduino to control a light emitting diode, turning the light on for 2.5s every 0.5s

Components Used

·         Light Emitting Diode (LED)

·         Resistor

·         Arduino

·         Solderless Board

Arduino Code

/* Blinking LED program
   LED turns on for 2.5 seconds with 0.5 seconds delay   
*/


int ledPin = 13;                  //led  connected to digital pin 13
void setup()                      // run once when the sketch start
{
  pinMode(ledPin, OUTPUT);
}

void loop()
{
  digitalWrite(ledPin, HIGH);     // turn on LED
  delay(2500);                    // lights on for 2.5s
  digitalWrite(ledPin, LOW);      // turn off LED
  delay(500);                     // light off for 0.5 sec
}
