Piano Solder Kit - Overview

Introduction​

The Piano Solder Kit is an educational electronics kit that teaches you the fundamentals of soldering and electronics by building a fully functional capacitive touch piano. Built around the classic ATmega328P microcontroller (which comes pre-programmed and ready to assemble) it generates tones and outputs sound to an external speaker through the LM386 Audio Amplifier for optimal loudness. The board also features an arpeggio mode with adjustable arpeggio speed control and multiple octave settings.
