Build a Real Playable Piano with Arduino Uno - Learn Frequencies and Music Note Generation

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 pressing a button and hearing a perfect C note, then playing a simple tune like "Twinkle Twinkle" on a breadboard piano you built yourself. This kit demystifies how electronics turn button presses into sound, teaching the physics of sound waves and the logic behind Arduino tone generation. It's a hands-on introduction to both coding and music theory.

What You'll Build

You'll assemble eight tactile buttons into an octave keyboard, wire them to an Arduino Uno, and program the board to produce accurate musical notes through a passive buzzer. By the end, you'll have a fully functioning electronic piano capable of playing any simple melody, from Sa Re Ga Ma to jingles.

What You'll Learn

• How Arduino's tone() function generates different frequencies for each musical note.
• The physics of sound: how frequency in Hertz translates to pitch, from 261 Hz (middle C) to 523 Hz (higher C).
• Reading button states and debouncing to ensure clean, single-note triggers.
• Crafting a simple musical interface with breadboard wiring and basic circuitry.

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for school students from CBSE Class 6-10 exploring physics and computer science, ATL Tinkering Lab participants building their first Arduino musical interface, and parents introducing electronics and coding to curious young minds. B.Tech freshers in ECE will also enjoy a quick, confidence-boosting build.

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.
