Touch TFT Piano Roll Kit with Arduino Uno
Touch TFT Piano Roll Kit: Visualize Every Note with Arduino Uno
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn a simple touch into a rolling musical score. With this kit, you'll build a real electronic instrument that not only plays sounds through a passive buzzer but also draws each note's timing, pitch, and duration on a bright 2.4-inch TFT screen, just like a digital audio workstation. The XPT2046 touch controller maps your finger taps to musical notes while the ILI9341 display plots them in real time, giving you a visual timeline of every performance.
What You'll Build
By the end of this project, you'll have a battery-powered touch piano that shows a scrolling piano roll. Tap the screen to trigger notes—the TFT instantly marks their position and length, so you can actually see rhythm patterns as they happen. It's a hands-on way to explore music theory, graphical displays, and sensor input all on one breadboard, and you'll walk away with a device that you can use to compose simple melodies or demonstrate timing concepts.
What You'll Learn
- How resistive touchscreens detect X and Y coordinates and convert them into playable notes
- The relationship between musical pitch and frequency, and how to program a passive buzzer to generate accurate tones
- Real-time data plotting on a TFT display—drawing and updating a dynamic piano roll interface
- Breadboard circuit assembly, including RC filtering with the included resistors and capacitors to clean audio signals

Who This Kit Is For
Young inventors from age 5 (with adult help) to 15 who want to see music come alive on a screen. It's ideal for ATL Tinkering Lab sessions, CBSE school science exhibitions, or a curious weekend project at home. If your child dreams of making their own instruments or you're introducing basic coding through a rewarding, visual output, this kit delivers a memorable first experience with Arduino and embedded design.
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 inside your box. Our AI build companion will walk you step by step, and we're also on WhatsApp for quick human backup.
Can my 6-year-old really build this?
Yes, with a parent or teacher assisting with the breadboard connections. The touch interface and visual piano roll keep younger kids engaged while they learn real circuits.
Why are resistors and capacitors included for a buzzer?
The passive buzzer creates cleaner, more pleasant tones when you add a simple resistor-capacitor filter. These components remove unwanted noise so your notes sound crisp.
What will the piano roll display look like when I play?
Notes appear as colorful bars that scroll horizontally, each bar's width matching how long you held the touch. It's a real-time timeline of your melody, just like music software.
XPT2046 touch screen draws notes on a piano roll as they are played. Visualises musical timing.
