The SparkFun Gram Piano Kit is a beginner-friendly soldering project that assembles into a working capacitive-touch musical keyboard. Once built, the piano plays a full octave of notes through touch-sensitive keys — no mechanical switches required.

Pre-installed firmware allows melody playback at the press of a button, and a soldered potentiometer lets you switch between octaves. The through-hole design with a moderate part count makes this kit ideal for those learning to solder who want a step up from basic projects.
