Description
This project involves building a small electronic piano based on an Arduino-compatible AZ-Nano V3 board with an Atmega328 CH340 chip as the central controller. The piano keys are built with microswitches (180 buttons) that trigger different musical notes when pressed. The buttons are connected to two MB-102 breadboards using 40 male-to-male jumper cables, which provide sufficient contact points for the wiring.
The sound output is provided by an AZ-Nano V3 board, which emits the note frequencies stored in the microcontroller via the 3-watt, 8-ohm loudspeakers as soon as a key is pressed. Power is supplied by a 9-volt battery with a clip-snap connector, giving the piano project mobility.
This project is a great way to learn about circuitry, microcontrollers and audio engineering while building a working mini piano. Ideal for beginners or as a fun electronics project for music lovers!
