Piano Solder Kit

The Capacitive Touch Piano Solder Kit teaches the fundamentals of soldering while you build a fully functional touch-sensitive musical instrument, making it ideal for beginners, STEM education, and hands-on electronics learning.

Learn the fundamentals of electronics and soldering while creating your own musical instrument. Perfect for beginners wanting to combine soldering education with entertainment, this kit teaches essential soldering techniques while building a fully functional capacitive touch piano.

With 12 touch-sensitive keys, volume control, and multiple octave settings, you'll create a musical instrument that demonstrates the magic of capacitive sensing technology. Take a look at our complete documentation for step by step assembly.

Built around the Atmega328P microcontroller, this kit introduces you to both hardware assembly and embedded programming concepts. The 12 capacitive touch sensors respond to fingers without mechanical switches, demonstrating touch interface technology. The first potentiometer provides volume adjustment, while the other one provides arpeggio speed control. The USB-C power connection ensures modern connectivity and power delivery for extended musical sessions.

This kit perfectly balances learning with entertainment, teaching essential electronics assembly skills while creating an amusing device. The capacitive touch technology introduces modern sensor concepts, while the code pre-programmed on the AtMega328p microcontroller is available to inspect on GitHub and provides insight into how embedded systems work.
