Mini Reverse Parking Sensor

🚗 Mini Reverse Parking Sensor

A custom ATmega328P-based Reverse Parking Sensor designed using PlatformIO, the Arduino Framework, KiCad, and Wokwi Simulation.

📌 Project Overview

The Mini Reverse Parking Sensor is an embedded systems project designed to assist drivers during reverse parking by detecting nearby obstacles using an HC-SR04 ultrasonic sensor.

The system continuously measures the distance between the vehicle and obstacles, providing both visual feedback through LEDs and audible warnings using a buzzer. The project demonstrates the complete embedded systems development workflow, including firmware development, schematic capture, PCB design, simulation, and manufacturing preparation.
