RADAR SYSTEM WITH ARDUINO

This is my second project in Arduino.

The Arduino RADAR System is a classic engineering project that mimics the operation of real-world sonar and marine radars. It uses sound waves to map the surroundings and displays the data on a graphical interface.

System Architecture

The project is split into two distinct parts:

  1. Hardware (The Scanner): An HC-SR04 ultrasonic sensor is mounted on an SG90 micro servo. The Arduino rotates the servo from 0 to 180 degrees (and back), taking distance measurements at every degree.
  2. Software (The Display): These distance and angle values are sent to a computer via the USB cable. A script written in Processing receives the data and draws a green "radar sweep," highlighting detected obstacles in red.

Components Needed

  • Arduino Uno/Nano: Controls the scanning movement.
  • HC-SR04 Ultrasonic Sensor: The "eyes" that emit and receive sound waves.
  • SG90 Micro Servo: Provides the 180-degree scanning motion.
  • Processing IDE: Software for the computer-side visualization.
  • Breadboard and Wires: For circuit connections.

Why Build This?

Building a RADAR system teaches you about inter-process communication (sending data between Arduino and PC) and basic trigonometry, as the Processing script must convert angle and distance (Polar coordinates) into X and Y positions (Cartesian coordinates) to plot them on the screen. It is a fundamental project for anyone interested in mapping and autonomous navigation.
