Micro:bit Reaction Timer Game Kit with BBC Micro:bit
Micro:bit Reaction Timer Game Kit: Build Your Own Reflex Testing Game with BBC Micro:bit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Press the button as fast as you can the moment the LED grid lights up — the Micro:bit then scrolls your reaction time in milliseconds. This simple but addictive game transforms learning about inputs, outputs, and timing into a race against your own reflexes. Perfect for kids who want to code something they can play with right away.
What You'll Build
You'll assemble a pocket-sized reaction timer that challenges anyone to beat their best score. After each button press, the LED display flashes your reaction time; the game then resets and repeats, building excitement with every round. In just over an hour, you'll have a working project and a great party trick.
What You'll Learn
- Program the BBC Micro:bit using MakeCode visual blocks — drag-and-drop, no prior experience needed
- Read button presses as digital inputs and control the 5×5 LED matrix as output
- Use the running time function to measure intervals in milliseconds
- Structure a game loop that resets, replays, and challenges your reflexes

Who This Kit Is For
Young students in CBSE Classes 5-8 exploring coding through tangible projects, ATL Tinkering Lab facilitators looking for a one-hour STEM win, or any curious kid who wants to measure how fast they really are. The activity fits perfectly into introductory electronics or coding clubs, and everything connects without soldering — ideal for little hands and short attention spans.
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 launch the AI build companion — it can see your setup and guide you step by step. If you still need help, message us on WhatsApp for a quick human assist.
Is this suitable for a complete beginner with no coding experience?
Absolutely. The project uses MakeCode blocks, a visual programming language that feels like snapping puzzle pieces together. No typing or syntax errors to worry about.
Do I need to solder or use special tools?
No soldering at all. The Micro:bit has built-in buttons and LEDs; just load the code, plug in the battery pack, and start playing.
Can I modify the game to add scoring or sounds?
Yes. Once you’ve built the basic timer, you can easily extend the code with MakeCode to show best scores, add countdown sounds, or even create a two‑player version with external buttons.
Press the button as fast as possible when the LED lights up — measures reaction time in milliseconds.
