7. PIN DESCRIPTION

8. L293D Driver
 L293D is a dual H-bridge motor driver integrated circuit (IC).
 Motor drivers act as current amplifiers since they take a low-
current control signal and provide a higher-current signal.
 L293D contains two inbuilt H-bridge driver circuits.
 In its common mode of operation, two dc gear motors can be
driven simultaneously, both in forward and reverse direction.

9. L293D Driver Features
 Voltage Range: 4.5 V to 36 V
 Separate Input-Logic Supply
 Internal ESD Protection
 High-Noise-Immunity Inputs
 Output Current 1 A Per Channel
 Peak Output Current 2 A Per Channel

10. SOLAR PANEL
 Solar panel is used to convert solar energy to electrical energy.
 In this the mono crystalline solar panel and is made from a
large crystal of silicon.
 Solar panels are popular in remote areas where electricity lines
are not available.

11. GEAR MOTOR
 Gear motors allow the use of economical low-
horsepower motors to provide great motive force at
low speed such as in lifts, winches, jacks and robotics.
 The reduction gear trains used in gear motors are
designed to reduce the output speed while increasing
the torque.
 Gear motors are used primarily in automotive
applications such as power window motors

12. REAL TIME CLOCK
 The DS1307 serial alarm real-time clock provides a full binary
coded decimal clock calendar that is accessed by a simple
serial interface. The clock provides seconds, minutes, hours,
date, month, and year information

13. LCD
 Liquid crystal display is an electronic display module.
 It has two registers command and data. The command register
stores the command instructions given to the lcd.
 The data register stores the data to be displayed on the lcd.

14. Crystal oscillator
 Crystal oscillator is an electronic circuit that produces electrical
oscillations at a particular designed frequency
 The crystal oscillator is generally used in various forms such as
a frequency generator, a frequency modulator and a frequency
converter.
 Keypads are a part of human machine interface
KEYPAD

15. ADVANTAGES
 Solar power is pollution free during use.
 The solar energy can be reused as it is non renewable resource
 Production end wastes and emissions are manageable using
existing pollution controls. End-of-use recycling technologies
are under development.

16. Applications
 Battery charger
 solar cooker
 In water treatment technologies

17. CONCLUSION
 Solar tracking system today offer an innovative method to track
the solar isolation and provide economic compatibility of the
generation of electric power where grid connections are
difficult to setup and costly.
 Here the tracking system is based on microcontroller with
effective systematic operation and the solar panel is rotated by
the dc gear motor effectively.
