Capacitive Touch Piano Kit with Arduino Uno: Make Music with Everyday Foil

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

With this kit, you’ll transform eight pieces of ordinary aluminium foil into a capacitive touch piano. Touch each foil pad to play a different note on the passive buzzer—no physical buttons required. It's an engaging introduction to electronics and music that works right out of the box.

What You'll Build

You'll build an 8-key piano keyboard that plays musical notes when you touch conductive foil pads. The circuit uses the Arduino’s capacitive sensing library to detect your touch, then plays corresponding tones through the passive buzzer. In under 3 hours, you’ll have a working electronic instrument that teaches core concepts in a fun way.

What You'll Learn

• How to read and write Arduino code for tone generation
• Capacitive sensing using analog pins and 1MΩ resistors
• Basic circuit prototyping on a breadboard
• Understanding of pitch, frequency, and sound output
