Polyphonic Ringtone Player Variant 2 Kit with Arduino Uno — an intermediate-level kit for teens.

Arduino Polyphonic Ringtone Player Kit – Build a Custom Music System That Plays Your Tones

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 1-5 days.

Imagine a compact device that stores up to 20 ringtones you’ve personally chosen, plays them at the press of a button, and displays the song name on a bright LCD. This kit lets you build exactly that—a polyphonic ringtone player powered by an Arduino Uno and a DFPlayer Mini. Whether you need a standout CBSE class project, a Smart India Hackathon prototype, or a hands-on way to understand audio processing and serial communication, every component arrives together, pre-verified to work as a complete system.

What You'll Build

You'll assemble a full-fledged music player that reads MP3 files from a microSD card and plays them through a dedicated speaker. Three tactile buttons control play/pause, next track, and previous track, while a 10kΩ potentiometer adjusts volume smoothly. The 16x2 I2C LCD shows the current ringtone name, turning a breadboard of wires into a polished device you can proudly present at school exhibitions, college mini-project evaluations, or ATL Tinkering Lab demos.

What You'll Learn

• Interfacing DFPlayer Mini with Arduino Uno using UART serial commands to control playback
• Capturing and displaying song names on an I2C LCD in real time
• Reading analog input from a potentiometer and mapping it to digital volume levels
• Organizing MP3 files on a microSD card and handling module power requirements with decoupling capacitors
