Arduino Speed Radar Gun Kit - Beginner STEM Project for Ages 10-12
Arduino Speed Radar Gun Kit - Measure Object Speed with Arduino Nano
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit turns a simple tabletop into a mini speed trap. You'll mount two IR sensors exactly 10 cm apart, connect them to an Arduino Nano, and watch an OLED display clock the speed of any object passing through. It's science class meets detective work - a perfect first project for curious young minds.
What You'll Build
You'll assemble a handheld speed measurement tool that detects break-beam interruptions. Roll a toy car, marble, or even your finger through the sensor gate, and the OLED instantly shows the speed in cm/s. The entire circuit plugs together on a half-size breadboard - no soldering, no mess, just clean prototyping.
What You'll Learn
- Wiring and programming an Arduino Nano from scratch
- Reading digital signals from IR break-beam sensors
- Calculating speed using distance / time logic
- Displaying real-time results on a 0.96-inch OLED screen

Who This Kit Is For
Young makers aged 10-12 who want a tangible intro to electronics. ATL Tinkering Labs in Indian schools will find it a ready-to-deploy STEM activity. Parents seeking a safe, fully guided first Arduino experience - just connect, upload, and start clocking speeds.
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 launch the AI companion that knows every step of this project. You can also message us on WhatsApp for direct support.
What can I use to test the speed gun?
Roll toy cars, marbles, or even wave your hand through the gate. Anything that breaks both beams in sequence works - the sensor spacing is preset for reliable readings.
Do I need any prior coding experience?
None at all. The pre-written code is provided, and the AI companion explains how to upload it to the Arduino Nano line by line.
Is this kit safe for a 10-year-old?
Yes. All parts run on low voltage from USB, connections are solderless, and the whole build happens on a breadboard with jumper wires.
Two IR sensors 10cm apart measure time between breaks to calculate object speed.
