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:
Vehicle which can be controlled remotely by an Android
The app sends commands via Bluetooth.
Commands received by Bluetooth modem connected to
Microcontroller controls motors.
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.
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
ALE: Address latch enable pin is an active high –output signals. If
we use multiple memory chips, then this pin is used to distinguish
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.
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.
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.
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
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
The robot can be used for surveillance.
It can be use to diffuse Time bomb by a safe distance.
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
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
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
