Description

Description: Pianos are heavy and can take about a year to make. What if you could have one that weighed only a few grams and took a very small amount of time to construct? The SparkFun Gram Piano is a beginners soldering kit that, once assembled, gives you with a musical keyboard that will leave you feeling like a modern day Mozart. This kit provides you with the ability to play an octave worth of notes using the capacitive touch keys, no strings or hammers required! The pre-installed software also lets you play a melody with the press of a button and switch octaves using a soldered potentiometer.

The Gram Piano is a simple through-hole kit with a fair part count, making it ideal for beginning solderers looking for a little more challenge. Like our other soldering kits, building and playing with this kit will teach you various skills related to soldering, electronics, and programming.
