Arduino Radar System Collage Project 2025
This project will simulate a basic radar system using Arduino, an ultrasonic sensor, and a servo motor. It will detect obstacles within a certain range and display their position on a screen.
Components Required:
Arduino Uno (or any compatible board)
HC-SR04 Ultrasonic Sensor (for distance measurement)
SG90 Servo Motor (to rotate the sensor)
OLED Display / LCD (optional) (to display results)
Buzzer & LEDs (for alerts)
Jumper Wires & Breadboard
Processing Software (for graphical radar display on PC)
Working Principle:
The servo motor rotates the ultrasonic sensor from 0° to 180° and back.
The ultrasonic sensor sends out sound waves and calculates the distance to objects by measuring the time it takes for the waves to return.
The data is processed and displayed as a radar-like output on either an OLED display or a graphical interface using Processing software.
If an object is detected within a certain range, an LED/buzzer can alert users.
