INTRODUCTION

This project aims at saving electricity.It's a very good and an innovativeidea.......to save our precious ENERGYRESOURCES. It utilizes our basicknowledge and the specific requirementof ELECTRICITY by the people of aparticular place...

BASIC CONSTRUCTS

It is basically a REAL TIME CLOCK that displays the

following data :

1. TIME

2.DAY

3.DATE

4.SUNSET TIME (IF ASKED TO DISPLAY)

5.SUNRISE TIME (IF ASKED TO DISPLAY)

It also enables us to set MULTIPLE ALARMS.

The sunset and sunrise time act as triggers for the

switching of lights.

It sets the light intensity required by the user at that time

automatically , and hence we make judicious use of

electricity(this prospect makes it an energy saving device).

Set the increment, decrement time and night mode time

Set alarm ( )

We can set upto 5 alarms in our digital clock.

Void Loop ( )

Set Sunrise and Sunset time according to the latitude, longitude and time zone

if not set

Digital clock display:

Displays :

1. time

2. date

3. day of week

4. sunrise time(if required)

5. sunset time (if required)

It automatically changes light voltages according to the present time and

the sunrise and sunset time.

DESIGN

It is designed using Arduino mega board , a USB cable connected to a computer.

IMPLEMENTATIONThis project is just a simulation of a real lifeproject . Here we will demonstrate it using theArduino kit .THE REAL PROJECT IS THEADVANCED FORM OF THIS PROJECTONLY....i.e. a single LED in this project will bereplaced by a number of street lights (to becontrolled) in the real project.

IMPORTANCE

This project is easy to use and install and has a

number of advantages.

All the settings are to be done by the user

during the time of installation only...once

installed, it requires no maintenance.

It describes the best way of saving electricity

without human intervention . It can also be

used as a digital clock that displays time and

date and has multiple alarm properties.

FUTURISTIC APPROACH

This project can be used anywhere in the

world, its database adjusts itself

according to the present latitude,

longitude and time zone entered by the

user. It can be used to automate street

lights in an housing society, hostel, park,

hotel corridors and in college premises or

anywhere you wish to install it.
