Students created a mobile controlled car that can be operated through a Bluetooth connection from an Android application. The car uses an Arduino board, motor driver, ultrasonic distance sensor, Bluetooth module, servo motor and other hardware components. The software on the Arduino allows it to communicate with the mobile application for remote control and uses the distance sensor to avoid obstacles. While the project goal of remote vehicle control was achieved, some components were damaged during testing and future work could explore additional applications like military robotics.

3. Introduction
Our project is mainly a bout controlling car movement
using mobile application .
This idea can be used in many fields as Entertaining
robot game for children or Spying purpose after
adding some further features such as a webcam
,so it may be used as a delivery tool for specific
type of services.

5. Problem Statement
After supplying the vehicle with voltage
» we turn the mobile Bluetooth
» using android application to connect with the
Bluetooth model on the vehicle.
» The vehicle will never crush into a wall because
existence of distance sensor

6. Goals
The vehicle has two mode’s
Bluetooth mode : using android application to control
with the Bluetooth model on the vehicle and to
moves in all directions
Non-Bluetooth mode : without Bluetooth control the
vehicle is moving forward
In the Bluetooth mode the vehicle will never crush into
a wall because existence of distance sensor

7. Project Algorithm

8. Hardware Components
● Arduino board (Arduino UNO)
● L293D motor driver chip.
● SRF04 Ultrasonic distance sensor
● HC-05 Bluetooth slave
● Prototyping board and cables
● USB cable
● Vehicle kit
● electronic speaker
● Servo Motor

9. Arduino board (Arduino Uno)
It will be the brain of the robot, as it will be
running the software that will control all the
other parts

10. Arduino Benefits
1. open-source
2. flexible
3. easy to use
4. inexpensive
5. online community

11. Software Part
The software which placed on PC we’ve used in
order to program and communicate with an
Arduino board.

12. • Example of connecting the USB cable with
Arduino module on port (com22 )

13. Using software
Some of libraries that we used
Ultrasonic library : to read data from ultrasonic
sensor and print the distance between
obstacles and the sensor.
Motor driver library : to test the motor .
Servo library : to control our servo motor.
Software Serial library : to get data sent from
Android application to Arduino on serial.

14. -Distance sensors send an ultrasonic signal forward
-Wait to receive a bounced signal. Depending on
how long the signal takes to bounce back the
approximated distance to an obstacle can be
calculated.
-We will use this little device to prevent the vehicle
from hitting walls or other obstacles in its way
Distance sensor

15. How to connect it with Arduino

16. • Which interact with mobile application to
control the direction of the vehicle.
It has four pins :
VCC (Power 3.3 – 6V)
GND
TXD
RXD
Bluetooth Module

17. • How to connect it with Arduino

18. A Servo is a small device that has an output
shaft
This shaft can be positioned to specific angular
positions by sending the servo a coded signal
Servo Motor

19. • How to connect it with Arduino

20. • It was used in the event of an obstacle in front
of the vehicle.
Electronic Speaker

21. • As single component
• As circuit
Motor Driver

22. ♦ represented in new things we must learn as
Arduino hardware component and the software
program used.
♦ some of component not available as a single
component so, we build it as a circuit for
example motor driver component
♦ Cost ,we’ve lost two Arduino’s and a servo
motor so we had to look for alternatives.
Problems

23. Conclusion and Future Vision
• we achieved blutooth control communication
between the mobile -via android application-
and the vehicle .
• The knowledge is ever expanding and so are
the problems which the mankind strive to
solve. In this spirit, it is hoped that the current
activity will lead to further enhancements. For
example; work on future for military purpose
by the robot.
