Autonomous Parallel Parking Car

Arduino Uno

L298N Driver

HC-SR04 Sensors

2-Wheel Chassis

1 Space Detection

Ultrasonic sensors scan for parking spots >27cm wide (calibrated via trial-and-error)

2 Initial Alignment

Car positions itself parallel to front vehicle (10cm threshold)

3 Reverse Maneuver

Wheels turn right (450ms pulse) while reversing until 15cm from curb

4 Final Adjustment

Wheels turn left (350ms pulse) to straighten with 5cm rear clearance

Power Management: Solved inconsistent motor power by testing series/parallel 18650 battery configurations
Sensor Fusion: Integrated 3 ultrasonic sensors with complementary detection zones
Precision Timing: Calibrated wheel turn durations through iterative testing
Localization: Implemented WiFi trilateration for slot detection (ESP32 prototype)
