Description

This program causes the led to run for 3 seconds, then pause 3 seconds, run for 2 seconds then pause for 2 seconds, run for 1 second then pause for 10 seconds. After this pause the loop begins again.

Components Used

• Light Emitting Diode (LED)
• Resistor

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

int time_stamp = 1000; // Incrementing in steps of 1 sec

//One sec is 1000 millisec

// The setup() method runs once, when the sketch starts

void setup()   {

// initialize the digital pin as an output:

// Happens only at the start of the simulation

pinMode(ledPin, OUTPUT);

}

// the loop() method runs over and over again,

// as long as the Arduino has power

//Power to the board comes from the USB2Serial converter

//The voltage of pulse from Pin13 is dropped over a resitor and given to the LED

void loop() // This is an infinite loop

{

digitalWrite(ledPin, HIGH); // set the LED on

delay(3000); // on for 3 seconds

digitalWrite(ledPin, LOW); //Set the LED pin to OFF

delay(3000); // off for 3 second

digitalWrite(ledPin, HIGH); // set the LED on

delay(2000); // on for 2 seconds

digitalWrite(ledPin, LOW); //Set the LED pin to OFF

delay(2000); // off for 2 second

digitalWrite(ledPin, HIGH); // set the LED on

delay(1000); // on for 1 seconds

digitalWrite(ledPin, LOW); //Set the LED pin to OFF

delay(10000); // off for 10 seconds
