Blind Stick Obstacle Detector Advanced Kit with Arduino Uno + Ultrasonic
Arduino Uno Space Docking Simulator Kit – Master Obstacle Detection & Safe Approach
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine guiding a spacecraft to dock with a space station—one wrong move and you're too fast. This kit transforms that high-stakes moment into a tabletop project. Using the HC-SR04 ultrasonic sensor and an Arduino Uno, you'll build a system that monitors approach speed, lighting a green LED for safe docking and a red LED for overspeed, just like real proximity alert systems in aerospace.
What You'll Build
Assemble a breadboard circuit with an ultrasonic sensor and two pairs of coloured LEDs. Program the Arduino to measure distance repeatedly and compute closing velocity. The system keeps the green LED steady when an object approaches within a safe speed tolerance, then instantly switches to red if the threshold is exceeded—creating a visual docking guidance display you can demonstrate in minutes.
What You'll Learn
- How to use an HC-SR04 ultrasonic sensor for distance and speed measurement
- Arduino programming for real-time sensor data processing and conditional logic
- Building circuits on a breadboard and understanding resistor values for LED brightness
- Interpreting proximity data to create safety-critical visual alerts, just like in aerospace docking systems

Who This Kit Is For
Young space enthusiasts aged 10-15 will love simulating docking sequences at home. CBSE Class 9-12 students can use it for physics practicals and sensor-based projects. ATL Tinkering Labs and early B.Tech ECE learners gain a complete introduction to proximity sensing and Arduino programming—all through a mission-critical space scenario.
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 to access the AI companion, or send a WhatsApp message. The companion knows every step of this exact project and can answer your questions instantly.
How does the kit simulate docking speed?
The HC-SR04 takes distance readings multiple times per second. The Arduino sketch calculates the change in distance over time to determine closing speed, lighting the red LED when it crosses your programmed threshold.
Can I repurpose this as a blind stick obstacle detector?
Absolutely. Modify the code to detect any obstacle within a fixed range—ignoring speed—and light the red LED or add a buzzer for alerts. The circuit is ready for both applications.
What programming knowledge is needed?
None. The kit includes pre-written code and wiring diagrams. The AI companion explains each line, so even complete beginners can follow along and learn C++ basics for Arduino.
Accessibility — HC-SR04 detects approach speed. Green LED when within docking tolerance, red when too fast.
