3. INTRODUCTION

An EMBEDDED SYSTEM is a computer system
with a dedicated function within a larger
mechanical or electrical system.

Embedded systems contain microcontrollers,
micro processors or digital signal processors

Some applications are digital watches and MP3
players, to large stationary installations like
traffic lights, factory controllers,

4. ABSTRACT OF THE
PROJECT

To track the sun’s position and to
capture the maximum solar energy
through solar panel.

And then this energy is converted to
electrical energy by photo voltaic effect

Solar energy is renewable and available
throughout the year.

5. 
The project contains two systems, one is
tracking and the other is controlling system.

Tracking system make angular rotation of
solar panel with the help of dc motor in
synchronous position of the sun.

The control system is designed with
efficient Microcontroller and RTC which
drives the tracking module at different
instants.

DESCRIPTION

LPC2148 SPECIFICATIONS:-
1. 40 KB of on-chip static RAM
2. 512 KB of on-chip flash
3. 2 UARTS
4. 60 MHz maximum CPU clock
5. 2 ADC’s and one DAC
6. High speed bus interfaces
7. Low power Real-Time Clock (RTC) with independent power

9. ARCHITECTURE of LPC2148:-

10. POWER SUPPLY:-
Transformer:- steps down high voltage AC mains
to low voltage AC.
Rectifier:- converts AC to DC, but the DC
output is varying.

11. Smoothing:- smoothens the DC from varying
greatly to a small ripple.
Regulator:- eliminates ripple by setting DC
output to a fixed voltage.

12. LIQUID CRYSTAL DISPLAY:-

13. 
GND, VCC, VEE :- vcc and vee are supplied with 5v supply and
ground is connected to ground

Register Select(RS):If RS=1 then data register is selected, user can display data on
lcd .
if RS=0 then command register is selected, commands can be
sent over lcd like clear display and positioning the cursor.

READ/WRITE:When R/W=1 then it is read mode
When R/W=0 then it is write mode

14. 
En (Enable) :-
The enable pin is used by the LCD to latch
information presented to its data pins. When
data is supplied to data pins, a high - to - low
pulse must be applied to this pin in order for
the LCD latch in the data pins. This pulse must
be a minimum of 450 ns wide.

D0 - D7 :-
The 8 - bit data pins, D0 - D7, are used to
send information to the LCD or read the
contents of the LCD's internal registers.

15. DC MOTOR DRIVER :-

17. DC MOTOR:Dc motor runs on dc current at speed of
3.5 rpm.
 Voltage required is 12v


18. POSITION KEYS AND KEYPAD:
Position keys are used to reset the solar
panel to its initial position

Keypad is used to set the time in RTC
module

19. REAL TIME CLOCK (RTC):
Counts seconds, minutes, hours, days,
day of the week, date, month, and year

This comes with a small power supply of its
own

This power supply helps RTC update time,
also after power supply is switched off

20. ADVANTAGES

They are beneficial as the sun's position in the sky
will change gradually over the course of a day and
over the seasons throughout the year.

In summer months with its long days of sunlight
available to capture and no energy will be lost.

Electricity production in tracking system is
relatively 30% to 40% more than stand alone solar
panels

21. DISADVANTAGES

Relatively high in cost than stand alone
solar panel systems

Regular maintenance is required

Weather condition can affect the system

More area is required for installation

22. APPLICATIONS

Remote places

Solar heating

In water treatment technologies

Cooking

Electricity production

23. CONCLUSION

A solar tracker is designed employing
the new principle of Real Time Clock, for
effective change of relative angle of
solar panel with the sun. By using this
method, the solar tracker was
successful in maintaining a solar array
at a sufficiently perpendicular angle to
the sun.
