Build a Car Parking Sensor with Arduino – Ultrasonic Sensor & LED Bar Graph Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Have you ever wondered how a car knows exactly how close you are to a wall? The CDN-KIT-1143 ultrasonic parking sensor kit lets you recreate that exact experience on your desk. You’ll wire an HC-SR04 sensor to an Arduino Uno, read distance values, and drive a 10-LED bar graph that lights up progressively as an object approaches — just like a real reverse parking aid.

What You'll Build

A fully functional proximity indicator on a breadboard. Place your hand in front of the sensor and watch the LEDs illuminate one by one until all ten glow at the closest range. The circuit precisely mimics the visual feedback used in modern cars, giving you a tangible understanding of object detection and embedded systems.

What You'll Learn

• Interfacing the HC-SR04 ultrasonic module using digital pins and understanding trigger/echo pulses.
• Writing Arduino code to measure echo time in microseconds and convert it to centimeters.
• Mapping distance ranges to LED states — lighting one to ten LEDs based on proximity.
• Managing multiple outputs (10 LEDs) on a breadboard and debugging sensor noise in real-time.

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for intermediate-level makers: CBSE Class 11-12 students tackling sensor-based physics or computer science projects, B.Tech ECE/EEE freshers learning embedded C and interfacing, and ATL tinkering labs that need a reliable kit for innovation challenges. Even participants in the Smart India Hackathon will find this a fast way to prototype distance-aware systems. It’s also a popular weekend build for hobbyists at IIT, NIT, VIT, and BITS Pilani.

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.
