The document outlines a graduation project focused on creating a Bluetooth-controlled Android car, detailing its objectives, system components, software tools, and flowcharts. The project successfully integrates a smartphone for car control through Bluetooth and suggests future enhancements like using Wi-Fi and adding an accelerometer. Issues mentioned include balance problems with the car's wheels and slow application performance, but the project opens avenues for various similar applications.

3. Introduction
• Bluetooth controlled android car consists of a cooperative
subsystems that rely on and Control another subsystem.
• The subsystems are divided into two main systems, the
car and the remote control.

4. Objectives
• Controlling robot car using smart phone.
• Design a system performs specific functions.
• Develop android application .
• Dealing with sensor interface with microcontroller
• Dealing with module interface with microcontroller

5. General description
• The final design will consist of vehicle and remote control,
The PIC will be our central processing unit .
• The vehicle and the remote control rely on communication
from one device to the other to produce a functioning
system.
• The system is expected to allow user to simultaneously
connect to vehicle through Bluetooth pairing between the
android device and the Bluetooth chip on the vehicle and
control the motion of the car.

6. • PIC 18f4550
• Power source
• Regulator
• led
• 2 DC motor
• L293 motor drive
• Car vehicle
• toothpick 2.1 Bluetooth module
• Android device
• LOGO vibration sensor
Components

7. Software tools
• c language to program the PIC microcontroller using
MikroC PRO for PIC – C complier for microchip
• java language to develop the mobile application using
ADT (Android Developer Tools) which is a plugin for
Eclipse that provides a suite of tools that are integrated
with the Eclipse IDE.

14. Problems
• car front wheels has a balance problem , one of the
wheels is higher than the other.
• Android application is slow and stop working so we need
to restart the application

15. Future work
• Using Wi-Fi technology instead of Bluetooth
technology.
• Add the accelerometer option to control the car

16. Conclusion
• We were able to complete our project and produced a
Bluetooth controlled android car that can be controlled
through a smart phone.
• This opens door for wide range of possible similar
applications.
1) Assistant for professor .
2) Assistant for housewife .
3) Electrically powered wheelchair
