3. INTRODUCTION
• The project is built around an 8051 microcontroller, IR remote
and an IR receiver.
• And a DC motor will also be interfaced to the controller through
a driver IC L293D.
• IR remote acts as the transmitter in this project.
• In the remote, 4 buttons are
• being dedicated to control the motor. Now, it is the job of the
controller to read the data
• received from the receiver and to perform the predefined task of
rotating the motor
• clockwise, anticlockwise and increasing, decreasing the speed of
the dc motor.

7. MICROCONTROLLER
• The prime use of a microcontroller is to control the operation using a fixed
program that is stored in ROM and that does not change over the lifetime of
the system.

9. POWER SUPPLY

10. TRANSFORMER
• A transformer is a device that transfers electrical energy from one circuit to
another through inductively coupled conductors—the transformer's coils
Transformer symbol Transformer

11. RELAYS
• A relay is an electrically operated switch. These are remote
control electrical switches that are controlled by another
switch, such as a horn switch or a computer as in a power train
control module, devices in industries, home based
applications.

12. DC MOTORS
• The brushed DC motor is one of the earliest
motor designs. Today, it is the motor of choice
in the majority of variable speed and torque
control applications.

13. APPLICATIONS
• To control a high-voltage circuit with a low-voltage signal, as
in some types of modems,
• To control a high-current circuit with a low-current signal, as
in the starter solenoid of an automobile,
• To detect and isolate faults on transmission and distribution
lines by opening and closing circuit breakers (protection
relays).
• Normally closed contacts. When a current is passed through
the relay coil, the relay operates and opens the contacts that
carry the supply current.

14. ADVANTAGES
• Easy to understand design
• Easy to control speed
• Easy to control torque
• Simple, cheap drive design

15. FUTURE SCOPE
• The work done can be further extended in future to design a
closed loop system which could control the speed to a more
précised value and error can be easily reduced by giving
feedback signal form the sensor to the controller using the
DAQ card.
• receive the system status and information via SMS.

16. CONCLUSION
• The speed control and the direction control of
the dc motor is achieved from the wireless and
radio frequency technology with Pulse Width
Modulation and H-Bridge.
• calibration procedure, but there is still value in
having a controller that can be built with no
exotic equipment.
