this is a final project which made a radar detector using arduino made in Btech

REPORT

2. What Are We Trying To Achieve?
We are basically developing a rangefinder device which is explained below.
A rangefinder is a device that measures the distance from the target to the
observer, for the purposes of surveying, determining focus in photography, or
accurately aiming a weapon .
In this technical project, we make a simple radar using the ultrasonic sensor, this
radar works by measuring a range from 3cm to 40 cm as non-contact distance,
with angle range between 15˚ and 165˚.The movement of the sensor is
controlled by using a small servo motor. Information received from the sensor
will be used by “Processing Development E”

3. Theoretical Approach:
(1) Using IO trigger for at least 10us high-level signal
(2) The Module automatically sends eight 40 kHz and detect whether there is a
pulse signal back.
(3) IF the signal back, through high level, time of high output IO duration is the
time from sending ultrasonic to returning.
Test distance = (high level time × velocity of sound (340M/S) / 2.

4. Hardware For This Project
(1)Arduino Board UNO Model.
(2)Ultrasonic sensor HC- SR04.
(3)Servo Motor tower pro micro servo 9g.
(4)Breadboard and Jump Wires.

5. Software Used:
● ARDUINO IDE
● PREPROCESSING 3

6. Circuit Diagram
We connected the Ultrasonic Sensor HC-SR04 to the pins number 10 and 11 on
the Arduino Board.
TrigPin = 10.
EchoPin = 11.
And the servo motor to the pin number 12 on the Arduino Board.

8. Connections
• SERVOMOTOR:
• RED SLOT TO 5V
• BLACK SLOT TO GROUND
• YELLOW TO PIN 12 ARDUINO
• SONAR:
• Vcc TO 5 V
• GND TO GROUND
• TRIG TO PIN 10 ARDUINO
• ECHO TO PIN 11 ARDUINO

9. Arduino Ide:
• Ardunio uno micro controller board was connected with via standard Usb
cable.
• The program code were written in C complier based Ardunio Ide.
• Sensor and Motor input and output were assigned into the program.

10. PROCESSING 3:
• Serial output data of Ardunio contains present status of rotation angle and
measured distance by sensor in centimeter.
• These three serial output parameters were transferred to processing
environment software.
• With the help of java script coding a visual interface was developed and using
the serial o/p parameter from ardunio, real time visualization of the dual
radar was developed.

11. Arduino Code:

13. Processing 3 code

16. Our Progress
– Hardware collected
– Arduino code completion
– Processing 3 code under development
– Area of detection due to 1 sensor is compromised so installing a new sensor
Depending upon 2 factors
1. Bigger sweep angle
2. A second sensor coupled

17. Add Ons:
We are trying to add certain additional functionality to our project.
● Use of another Ultrasonic sensor to increase the sweep angle to 355˚ approx.
● Establishing a connection between Arduino through the use of bluetooth
transmitter.
● Get the output on our smartphone screen along with getting it on our
computer screen through the development of an mobile application built
through Android.
