They can now be replicated using electronic circuits. This device converts traditional pianos or other instruments into digital forms using electronic components. The source code can be modified to create various digital instruments, such as drums or flutes, by adjusting the output sound, tone, and frequency.
This device uses an ESP32 board for tone processing, with transistors amplifying the output. You can create or modify code in any IDE, such as Arduino IDE, ESP IDF, Micropython, or Smowcode. For quick coding, Smowcode has been used in this device. Fig. 1 shows the author’s prototype on a breadboard. The required components are listed in Bill of Materials table.
