Self-Parking Car Kit with Arduino Mega + Encoder
Build Your Own Self-Parking Car with Arduino Uno R3 — Autonomous Parallel Parking Robot
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Parallel parking is one of the trickiest driving maneuvers — now automate it entirely. This kit guides you to build a 2WD car that uses three HC-SR04 ultrasonic sensors and a proportional servo steering mechanism to detect side gaps, calculate the perfect steering angle, and smoothly slide into a parking spot without a single line of manual control. The result is a miniature autonomous parking system that mirrors how real‑world self‑parking cars operate, giving you hands‑on experience with control logic, sensor integration, and embedded programming.
What You'll Build
You’ll assemble a compact robotic car on a 2‑wheel‑drive chassis that scans its right side for a gap large enough to fit. Once a suitable space is found, the rear sensor takes over to align the vehicle, and an SG90 servo smoothly steers the front wheels into the spot. The car stops when the rear sensor confirms a safe distance, completing a perfect parallel park every time. This isn’t a line‑following bot — it’s a true autonomous decision‑making system that adapts to different gap sizes.
What You'll Learn
- How to use multiple HC-SR04 ultrasonic sensors simultaneously for spatial awareness and gap measurement.
- Writing Arduino code for proportional servo control to steer wheels precisely based on sensor feedback.
- Integrating an L298N motor driver to manage bidirectional DC motor control for forward and reverse motion.
- Debugging real‑time sensor fusion logic and tuning parking algorithms on an embedded platform.

Who This Kit Is For
This intermediate‑level project is ideal for CBSE Class 11‑12 students taking Computer Science or Physics who want to explore robotics beyond theory. B.Tech ECE & EEE undergrads will find it perfect for mini‑project submissions, while teams preparing for Smart India Hackathon or ATL Tinkering Lab mentors can use it as a complete sensing‑actuation module. Even IIT, NIT, VIT, and BITS Pilani students working on autonomous vehicle prototypes will appreciate the self‑contained, no‑solder design.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to open the AI companion; it can diagnose your circuit, explain code line by line, and even suggest sensor placement tweaks. If you prefer human help, our WhatsApp support answers within a few hours on working days.
Do I need prior coding experience with Arduino?
Basic familiarity with the Arduino IDE and uploading sketches will help you move faster, but the included code is fully commented, and the AI companion walks you through every logic block — you can learn as you build.
Can the car parallel park on the left side too?
Yes. By repositioning the two side‑facing HC‑SR04 sensors to the left, you can modify the detection logic; the AI companion provides guidance and a modified code snippet for left‑side parking.
What if an ultrasonic sensor gives false readings?
Cross‑talk between sensors is a common issue. The companion will show you how to add short delays between sensor pings and place capacitors across the power lines, which usually eliminates erratic readings completely.
HC-SR04 sensors on sides and rear auto-park the car into a parallel gap with proportional servo steering.
