sonar radar system using arduino, servo & ultrasonic (hc-sr04) - interactive display

Although they depend on two very different types of wave transmission, radio detection and ranging (RADAR)
And sound navigation and ranging (SONAR)
They are all remote sensing systems with important military, scientific and commercial applications.
When active sonar emits sound waves, the radar emits sound waves (i. e. , sound)waves.
In both systems, these waves return echoes of certain features or targets that allow the determination of important attributes and attributes of the target (i. e.
, Shape, size, speed, distance, etc. ).
Because sound waves are strongly attenuated (diminished)
Radar signals are mainly used for ground or atmospheric observation in water.
Because sonar signals can easily penetrate water, they are ideal for underwater navigation and measurement. ULTRASONIC (HC-SR04): The HC-
The SR04 ultrasonic sensor is a very affordable proximity/distance sensor, mainly used for object avoidance in various robot projects.
It basically makes your Arduino eye/space sense and prevents your robot from falling off the table.
It is also used for turret applications, water level sensing, and even as a parking sensor.
This simple project will use HC-
The SR04 sensor with Arduino and processing sketches can provide a neat and interactive display on the computer screen.
Servo: the servo motor is a rotary actuator or linear actuator that can accurately control the angle or linear position, speed and acceleration.
It is connected by a suitable motor with a sensor for position feedback.
ARDUINO: Arduino is a computer hardware and software company, project and user community that designs and manufactures a microprocessor suite for building digital devices and interactive objects that can sense and control physics
