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.
Key Features
- Capacitive Touch Keys – Play a full octave of notes by touching the pads
- Pre-Installed Software – Melody playback mode and octave switching included
- Potentiometer Control – Switch between octaves after assembly
- Through-Hole Design – All components are through-hole for easy soldering
- Beginner Soldering Kit – Moderate part count for new solderers looking for a challenge
Ideal For
- Learning to solder with a fun, interactive project
- STEM education and electronics workshops
- Gifts for aspiring makers and musicians
Jargon buster
Plain-language definitions for the technical terms used above.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
