About the Project
In this project, we are going to design an
Arduino radar project using Ultrasonic Sensor
for detection.
An Arduino microcontroller makes electronics
more discipline.
This Arduino radar project aims to achieve a
radar system prototype based on an Arduino
board that detects stationary and moving
objects

3. How RADAR works.
The basic principle of operation:
A radar is an electromagnetic sensor that is used to detect and locate an object.
• The word RADAR means Radio Detection And Ranging. Radar is an object detection system
that uses microwaves to determine the range, altitude, direction, and speed of objects within
about a 100-mile radius of their location.
• The radar antenna transmits radio waves or microwaves that bounce off any object in their
path. Due to this, we can easily determine the object in the radar range.

4. Components Description:
Arduino
Arduino consists of both a physical programmable circuit board (often referred to as a
microcontroller) and a piece of software, or IDE that runs on computer, used to write
and upload computer code to the physical board.
The Arduino sends a HIGH pulse on the TRIGGER pin of the sensor to regenerate a series of
ultrasonic waves and returns in the opposite direction towards the sensor pin ECHO. The
sensor detects the width of the pulse to calculate the distance.
The signal on pin ECHO the sensor remains at the HIGH position during transmission
The LCD display displays the calculated distance and the angle of rotation. The buzzer is an
additional component, it rings when there is a detection along with LEDs.

5. Ultrasonic Sensor
Ultrasonic Sensor
• An ultrasonic sensor is a proximity sensor
that is used to measure the distance of a
target or object.
• It detects the object by transmitting
ultrasonic waves and converts the reflected
waves into an electrical signal
• These sound waves travel faster than the
speed of the sound that humans can hear.

6. • Servo Motor
 The servo motor is a simple DC motor that can
be controlled for specific angular rotation with
the help of additional servomechanism.
This motor will only rotate as much we want
and then stop.
 The servo motor is a closed-loop mechanism that
uses positional feedback to control the speed and
position
 The servo motor is unlike a standard electric motor
which starts and stops according to the power input
According to the signal, the servo motor will work

7. Implementation and Output
 After uploading the code, the servo motors start running from 0 to 180
degrees and again back to 0 degrees. An ultrasonic sensor also rotates
along with the servo as it is mounted on the motor.
 Now, run the processing code. If your code is right then, you will get a new window.
This is the graphical representation of data from the Ultrasonic Sensor is
represented in a radar type display.
 If an ultrasonic sensor detects any object within its range, you can see the same on the
graphical representation. The below gif shows the output of the Arduino radar project

8. USES AND FUTURE OF RADAR
Modern radar has many applications that impact our daily lives in ways that are not always
obvious.
• The antennas that will bring us 5G and 6G Internet are
electronically scanned.
• The weather forecasts that we rely on could not exist without
specific ground and space-based radars.
• Applications are also being found for radar in the medicine and
emergency management fields
• Radar technology is further evolving towards a 4D imaging radar capable
of providing a dense 4D point cloud .
• Radars are a key element of the sensor suite in ADAS and autonomous mobility.
