Ultrasonic Radar Project: Proximity-Based Alarm System

This project seeks to apply the sonar capabilities of the Arduino Uno to create a proximity-based alarm system that can be used in a number of applications, though primarily intended for car safety features. Created utilizing the Arduino Starter Kit, the Arduino IDE, and the Processing IDE with a computer, this alarm system will activate if an object passes within 30 cm of its sensor. The Arduino board is programmed using the C++ language, while the processing code is written in JavaScript. There are two different codes written for the Arduino: one for a rotating sensor, which could primarily be used for security purposes, and one for a stationary device to be used for vehicular anti-collision systems. Through testing, it was discovered that both of these codes work as intended. With refinement, they could be used in conjunction with existing technology, or implemented on top of older systems that do not yet integrate modern technology.
