This project involves building an Arduino-based ultrasonic radar system. The system uses an Arduino UNO, ultrasonic sensor, and servo motor. It sweeps the ultrasonic sensor in an arc using the servo motor to detect objects and measure their distance. The distances measured are then visualized in a Processing application to function like a radar display. Potential applications include security systems, interactive exhibits, parking assistance, and robotic navigation.

5. Abstract:
 The ultrasonic sensors are used to
detect the object, to measure the
distance of the object and has many
applications.
 The Ultrasonic sensor provides the
easiest method of object detection and
gives the perfect measurement
between stationary or moving objects.

6. Abstract
 Radar is a long-range object detection
system that uses radio waves to
establish certain parameters of an
object like its range, speed and
position.
 Radar technology is used in aircrafts,
missiles, marine, weather predictions
and automobiles.

7. Components
 Arduino UNO
 HC-SR04 Ultrasonic Sensor
 Servo Motor
 Mounting Bracket for Ultrasonic Sensor
(optional)
 Connecting Wires
 Jumper Cables
 5V Power Supply
 USB Cable (for Arduino)

8. Introduction
 The Arduino Radar Project is more of a
visual project than it is a circuit
implementation. Of course, I will be
using different hardware like Arduino
UNO, HC-SR04 Ultrasonic Sensor and a
Servo Motor but the main aspect is the
visual representation in the Processing
Application.

9. Introduction
 Even though the title says Arduino
Radar Project, technically the project is
based on Sonar technology as I will be
using an Ultrasonic Sensor to
determine the presence of any object
in a particular range.

11. Cont…
 The control pin of the servo is connected to Pin 11
 the Arduino while the TRIG and ECHO Pins of the
Ultrasonic Sensor are connected to Pins 9 & 10 of
Arduino respectively.
 After making the connections, there is one important
step in the construction you need to perform (not
mandatory).
 Since the Ultrasonic Sensor must sweep an arc of
1800 (with the help of the Servo), I have used a
mounting bracket as shown in the image below to fix
the Ultrasonic Sensor.
 As the bracket and the Ultrasonic Sensor adds weight
to the servo, make sure to use a double-sided-tape to
fix the Servo firmly to the surface.

12. working
 Initially, upload the code to Arduino after making the
connections.
 You can observe the servo sweeping from 00 to 1800 and
again back to 00. Since the Ultrasonic Sensor is mounted
over the Servo, it will also participate in the sweeping
action.
 If you note the Processing Sketch, I have used the output
display size as 1280×720 (assuming almost all computers
now-a-days have a minimum resolution of 1366×768) and
made calculation with respect to this resolution.
 Now, run the sketch in the Processing and if everything
goes well

13. Application’s
 Used to develop security systems.
 Used interactive animated exhibits.
 Used in parking assistance systems.
 Used in robotic navigation.
