Arduino Xylophone Kit: Build a Robot Musician with Servo & Buttons

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 a button and a tiny wooden mallet swings down to strike a xylophone key — that’s the magic of this musical robot. The Arduino Uno reads an octave of tactile button inputs and sends precise angles to the SG90 servo, turning a simple finger press into a real, ringing note. Whether you use a store-bought toy xylophone or craft one from metal spoons and aluminium strips, this project blends coding, mechanics, and sound into a single build that works right out of the box.

What You'll Build

You will build a complete robot musician. Eight buttons sit in a row like a piano keyboard; pressing any button commands the servo to move its arm and strike the matching key on your xylophone. The xylophone itself can be a commercial instrument or a DIY creation made from household objects — the AI companion includes a guide for building one with glasses of water, metal bars, or different-sized spoons. The robot’s frame and striker are assembled on the breadboard, and once programmed, the whole system runs on a 9V battery, ready for impromptu recitals.

What You'll Learn

• Wiring and programming an Arduino Uno to read multiple button inputs without interference
• Controlling a servo motor to position its arm precisely on different notes
• Using pull-up and pull-down resistors to keep button signals clean and reliable
• Writing a simple music sequencer in the Arduino IDE that maps button presses to note pitches

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

A 5‑year‑old can help assemble the buttons while a 15‑year‑old writes the code — this kit scales across ages. It fits perfectly into CBSE Class 11‑12 electronics practicals, B.Tech ECE/EEE introductory microcontroller labs, ATL Tinkering Lab activities, and science fair exhibits. Hobby clubs and summer workshops across India frequently use this exact project to introduce robotics and musical computing.

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.
