 Kids Piano Circuit 8 Keys Version using arduino Uno

To simulate a simple 8-key piano using Arduino Uno in Tinkercad. Each key (push button) plays a different musical note through a piezo buzzer when pressed.

Notes and Frequencies Mapped:

Button	ArduinoPin	Note	Frequency(Hz)
1	D0	C4	60
2	D1	D4	59
3	D2	E4	57
4	D3	F4	55
5	D4	G4	53
6	D5	A4	52
7	D6	B4	50
8	D7	C5	48

When a child presses any of the 8 buttons, the piezo buzzer plays a corresponding note (C4 to C5), making it a simple, interactive piano toy. It's a great way to introduce kids to electronics and music!
