The project is used to detect obstacles using an ultrasonic sensor and plot the data on a radar screen using Processing.

EXPANDED TECHNICAL DETAILS

Acoustic Spatial Mapping

This classic project replicates the functionality of a professional military radar using ultrasound pulses.

  • Servo-Sync Triangulation: The Arduino controls a Micro Servo (SG90) to rotate an HC-SR04 ultrasonic sensor in a 180-degree arc. Every 1 degree of rotation, the Arduino triggers a pulse and records the distance to the nearest object.
  • Serial Visualization Bridge: The data (Angle and Distance) is sent in real-time to a Processing script. This script draws a vivid "Radar Grid" on a computer screen, showing detected objects as glowing blips in their relative spatial positions.

Field of View (FOV) Optimization

  • Scanning Logic: The firmware includes a "Reverse Sweep" function and adjustable scanning speed, allowing users to balance between high-resolution mapping and fast object detection.
