4. INTRODUCTION OF PROJECT:
 Bluetooth controlled car is a robot
which is built using 8051
microcontroller in which
communication is done via
Bluetooth and programming is
done in embedded C language.

5. OVERVIEW OF PROJECT:
 What?
 Vehicle which can be controlled remotely by an Android
smart phone.
 How?
 The app sends commands via Bluetooth.
 Commands received by Bluetooth modem connected to
microcontroller.
 Microcontroller controls motors.

6. BLOCK DIAGRAM:

7. MICROCONTROLLER:
 Introduced in 1981 by Intel corp.
 8 bit microcontroller.
 4K bytes internal ROM.
 128 bytes internal RAM.
 Four 8-bit I/O ports (P0 - P3).
All four ports are bidirectional.
 Max. of 64k bytes of on chip ROM.

8. PIN DISCRIPTION OF 8051 MICROPROSESSOR :

9. CONT::
 There are 40 pins which are dedicated to several functions such as
I/O, address, RD, WR, data and interrupts.
 A total of 32 pins are set away into four ports such as P0, P1, P2,
and P3. Where each port contains 8 pins.
 XTAL1, XTAL2: X2 AND X1 pins are input output pins for the
oscillator. These pins are used to connect to the microcontroller.
 PSEN: This pin is used to enable external program memory. If we
use an external ROM for storing the program, then logic 0 appears
on it, which indicates microcontroller to read data from the
memory.

10. CONT::
 ALE: Address latch enable pin is an active high –output signals. If
we use multiple memory chips, then this pin is used to distinguish
between them.
 EA: It have to use multiple memories then the application of logic 1
to this pin instructs the microcontroller to read data from both
memories –first internal and then external.

11. BLUETOOTH:
 Bluetooth Technology is standard for short-range radio communication.
 It is a low cost bi-directional (2 ways) wireless interface between
mobile devices that provides low power consumption.
 Bluetooth Transceiver referring to Bluetooth Transmitter and Receiver
and every Bluetooth node have Bluetooth Transceiver.

12. CONT::
 The aim is to eliminate the usage of cables. Bluetooth
system operates in worldwide unlicensed 2.4GHz
Industrial-Scientific-Medical (ISM) frequency band.
Bluetooth devices can form a network.

13. MOTOR:
 Motor control requires full processor attention
Monitor motor speed
Continuously adjust motor voltage to minimize error
between desired and actual motor speeds
Essentially a digital feedback control system
 Want to avoid this additional hardware and software
complexity.

14. POWER SUPPLY
 A device or system that supplies electrical or other types of energy to an
output load or group of loads is called a power supply unit or PSU.
 Here in our application we need a 12v DC power supply for all
electronics involved in the project.
 This requires step down transformer, rectifier, voltage regulator, and
filter circuit for generation of 12v DC power.

15. SOFTWARE USED:
 Kiel Software to provide you with software development tools for
8051 based microcontrollers.
 With the Kiel tools, you can generate embedded applications for
virtually every 8051 derivative.
 Kiel software converts the C-codes into the Intel Hex code.

16. APPLICATIONS :
 It can be used by police and army for spying
 This robot can be used in borders for detecting and disposing hidden
land mines.
 The robot can be used for surveillance.
 It can be use to diffuse Time bomb by a safe distance.

17. ADVANTAGES:
 The robot is small in size it easy to carry .
 Bluetooth is actually cheap technology which help to reduce
the cost of project
 It need to low power for working so it is Low energy
consumption device
 It can operate by remote a long distance
 This device has low weight so it run faster

18. FUTURE DEVELOPMENT:
 We can interface sensor to this robot so that it can monitor some
parameters.
 We can add wireless camera to this robot.
 IT can be powered by solar energy
 IT can be used radar system to see the objective inside a building
