BBC Micro:bit Noise Level Meter Kit - Clap & Shout Bar Graph
Watch Sound Come Alive: Micro:bit Noise Level Meter Kit 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.
Imagine clapping your hands and instantly seeing a row of lights on the micro:bit's LED matrix dance to the loudness. This kit transforms the BBC micro:bit v2's built-in microphone into a real-time noise level meter, turning abstract sound waves into a blinking, colorful bar graph that even an 8-year-old can program in under two hours.
What You'll Build
A portable noise level meter that displays a bar graph - the louder the sound, the more LEDs light up. Your child can carry it around, test whispers vs. shouts, and see science in action. The kit includes everything needed: the micro:bit, cable, battery holder, and batteries, so the meter works anywhere without a computer once programmed.
What You'll Learn
- How the micro:bit v2's MEMS microphone captures sound and turns it into digital signals.
- Basic block-based coding with MakeCode to read microphone levels and control the 5�5 LED display.
- Understanding of sound amplitude and how bar graphs represent real-time data.
- Debugging simple code and tweaking sensitivity so the meter responds to claps but not background noise.

Who This Kit Is For
Perfect for CBSE Class 5-8 students exploring microcontrollers, Atal Tinkering Lab projects for primary graders, or any curious 8-10-year-old who wants to turn a clap into a light show. It's also a great gift for parents looking to introduce coding without a screen-heavy experience - the child can build, then play with the meter independently.
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 open the AI companion. It will guide you step by step, and you can always reach us on WhatsApp for real-time help.
Can this kit be used without any coding experience?
Yes, it's built for absolute beginners. The AI companion provides MakeCode block-by-block instructions, so no prior coding is needed.
Does the micro:bit need to stay plugged into a computer?
No, once you load the program, the micro:bit runs on the included AA batteries. Your child can take the noise meter anywhere.
What if the bar graph doesn't show properly?
The AI companion will walk you through common fixes - often it's just a matter of adjusting the microphone threshold. WhatsApp support is also available.
Clap or shout and watch a bar graph on the LED matrix respond to sound - uses micro:bit's built-in microphone.
