Micro:bit Light Theremin Kit - Build a Musical Instrument with BBC Micro:bit
Wave Your Hand to Create Music with the BBC Micro:bit Light Theremin Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact light theremin project. Shipped from Bengaluru in 3-5 days.
Imagine playing music without touching anything-just moving your hand over a light sensor to control the pitch. With this BBC Micro:bit Light Theremin Kit, young makers turn an LDR and a buzzer into a real theremin. It is perfect for kids aged 8-10 who love music and tinkering.
What You'll Build
In about 2-3 hours, you will build a working light theremin that responds to hand shadows. Connect the LDR in a voltage divider circuit on the half breadboard, program the micro:bit to read light levels and map them to musical tones played through the piezo buzzer. The result is a unique instrument that changes sound as you wave your hand closer to or farther from the sensor.
What You'll Learn
- How a light-dependent resistor (LDR) changes resistance with light intensity
- Building a voltage divider circuit to read an analog sensor with the micro:bit
- Programming sound output and pitch mapping in MakeCode or Python
- Troubleshooting physical computing projects and experimenting with sensor placement

Who This Kit Is For
This kit is ideal for curious kids aged 8-10 exploring STEM at home or in school labs. It aligns well with CBSE Class 5-7 science projects and ATL tinkering lab activities. It also makes a great gift for young learners participating in school-level maker fairs or simply wanting to create their first electronic musical instrument.
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?
The QR code on the box links to an AI companion trained on this exact kit. You can also reach us on WhatsApp for live human support.
Do I need any prior programming experience?
No, this kit is designed for complete beginners. The micro:bit block-based MakeCode editor makes coding a simple drag-and-drop experience.
Can I modify the theremin to play different scales?
Absolutely. Once you've built the basic project, you can change the pitch mapping in code to play pentatonic, major, or even custom scales, experimenting with new sounds.
Is the micro:bit included, and which version?
Yes, you get the BBC Micro:bit v2, the latest version with built-in speaker and microphone, though the project uses an external buzzer for the theremin effect.
Wave your hand over an LDR to change the pitch of a sound - a light-controlled musical instrument built with micro:bit.
