mini electronic keyboard

Overview

A simple electronic keyboard based on STC8G1K08 microcontroller.
Using ADC to detect the touch buttons, the TC8002 amplifier drives the speakers to improve the sound quality.

The painting method of touch button silk screen is directly learned from the design of a friend of this website: https://oshwhub.com/47uF/mini_piano.
I would like to express my respect.
