Big Button Sound Machine Kit
Big Button Sound Machine Kit — Press Big Buttons, Play Different Sounds, No Coding Needed
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 the delight on a child’s face when they press a huge coloured button and their own hand-built machine plays a melody. This kit turns a handful of components into a four-button sound gadget — each button triggers a different pre-programmed UM66 melody IC, driving a piezo buzzer. With no coding or soldering, it’s the perfect first electronics project that delivers instant audio gratification and a sense of ownership.
What You'll Build
Your child will assemble a working sound machine on a breadboard. Four jumbo push buttons are wired to four UM66 melody ICs, each playing its own tune through a common piezo buzzer. The moment the batteries are inserted, pressing any button produces a clear sound — no setup, no upload, just immediate cause-and-effect fun.
What You'll Learn
- How to place components on a breadboard and complete a circuit
- How push buttons control electricity flow to trigger a sound chip
- How a piezo buzzer converts electrical signals into audible tones
- The role of resistors in protecting components and shaping sound

Who This Kit Is For
Young explorers aged 6-8 in India who are stepping into electronics for the first time. Parents who want a screen-free, hands-on weekend activity. Educators in ATL Tinkering Labs looking for a safe, minimal-prep project for junior sections. Also a fantastic birthday gift that blends play with early STEM skills — no prior experience needed.
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 guides you step by step. If you need a human hand, drop us a WhatsApp — our team of engineers replies quickly.
Can a 6-year-old really build this without help?
Most children at this age succeed with a parent nearby for the first few minutes. The AI companion’s visual instructions and the large, easy-to-handle parts make it straightforward.
Do the sounds stay the same every time?
The four UM66 ICs play fixed melodies, but kids can swap the IC positions to change which button plays which tune. You can also replace any IC with a different UM66 variant for new sounds later.
Is it safe for my child?
Absolutely. The kit runs on two AA batteries (3V), there’s no soldering, and all components are large, non-toxic, and enclosed in a breadboard-based setup. The piezo buzzer volume is comfortable for indoor play.
Four big coloured buttons each play a different sound — built around a pre-programmed sound IC, no coding needed.
