How to Make a Radar Using Arduino & Ultrasonic Sensor.
Introduction:
In this project, I will show you how to design a simple
Radar Application using Arduino and Processing. This Arduino Radar Project is
implemented with the help of Processing Application. 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.
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. 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 Nano,
HC-SR04 Ultrasonic Sensor and a Servo Motor but the main aspect is the visual
representation in the Processing Application.
Circuit Diagram:
If you look at the circuit diagram, the design of the circuit for this project is very simple. The control pin of the servo is connected to Pin 12 of the Arduino while the TRIG and ECHO Pins of the Ultrasonic Sensor are connected to Pins 10 & 11 of Arduino respectively. A separate 5V power supply (with common GND) is given to the Servo Motor and the Ultrasonic Sensor.
