Build your own DIY Radar System using this fun and educational kit powered by Arduino and an ultrasonic sensor! The system scans the environment and displays obstacle positions on your computer screen in real-timeβjust like a real radar!
π§° Whatβs Included:
-
1x Arduino Uno (or compatible)
-
1x HC-SR04 Ultrasonic Sensor
-
1x SG90 Servo Motor
-
1x Jumper Wires Set
-
1x USB Cable for Arduino
-
1x Cardboard/Plastic Mount (for sensor & servo)
-
1x Radar Interface Code (Processing sketch)
-
1x Assembly & Code Guide (PDF)
π How It Works:
-
The servo motor rotates the ultrasonic sensor in an arc (typically 0Β° to 180Β°).
-
The HC-SR04 measures the distance to any object in its path.
-
Data is sent to the Arduino, which processes the angle and distance.
-
Processing software on your PC reads the serial data and draws a live radar-style visualization, plotting detected objects in a circular sweep.
π‘ Key Features:
-
Live Radar Display using Processing (with arcs, dots, and sweeping effect)
-
Adjustable scanning angle and delay
-
Great for STEM learning and school projects
