Nano Reaction Timer Game Kit with Arduino Nano + LED
Build Your Own Arduino Nano Reaction Timer – A Fast-Reflex Game That Fits in Your Pocket
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
An LED flashes at random moments – how fast can you press the button? This kit transforms an Arduino Nano, a tiny OLED screen, and two buttons into a fully playable reaction timer game. Measure every reflex down to the millisecond, see your personal best on the display, and challenge everyone around you to beat that score. All in a breadboard-friendly format that requires no soldering.
What You'll Build
You will assemble a compact handheld game that tests and displays your reaction speed. The 0.96‑inch OLED shows your latest reaction time in milliseconds and remembers your all‑time best. A random delay between the LED flash and the button press keeps the game unpredictable and fun. Power it from a 9V battery and take it anywhere – a perfect first project that actually works like a toy.
What You'll Learn
- Reading button inputs and debouncing them in Arduino code
- Controlling an I2C OLED display to show live scores
- Using non‑blocking timers (millis()) to create random delays
- Storing and updating high scores in EEPROM

Who This Kit Is For
Perfect for students aged 10+ stepping into physical computing. CBSE Class 11–12 learners will grasp timing logic and display integration in one afternoon. B.Tech ECE/EEE freshers can use it as a hands‑on breadboard exercise. ATL Tinkering Lab members and IoT hobbyists will enjoy the instant game‑like feedback. Even curious kids and parents can build together – no soldering, no complicated tools.
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.

How does the reaction timer measure time?
The Arduino Nano uses the millis() function to track the moment the LED turns on and the instant you press the button. The difference is displayed on the OLED in milliseconds.
Can I modify the code to use a different display?
Absolutely. The provided Arduino sketch is well-commented, so you can swap the OLED for a serial monitor output, an LCD, or even add sound. The AI companion can guide you through those changes.
Do I need to solder any parts?
No. Every component plugs into the included 170‑point breadboard using the pre‑cut M‑M wires. It's completely solder‑free, making it safe and easy for beginners.
LED flashes randomly. Button records reaction time in ms. OLED shows result and personal best. Compact game.
