Arduino Project: Using the tone() Function for Buzzer Music

The tone() function in Arduino is a useful tool for playing notes on passive buzzers. By combining multiple calls to the tone() function, we can create melodies and play songs. To use the tone() function, follow this syntax: tone(<PIN>, <FREQUENCY>) For example, to play the C7 note on a buzzer connected to pin 8, use the following code: #define NOTE_C7 2093 tone(8, NOTE_C7) Please note that frequency is measured in hertz (Hz)....
