melodies

In this Arduino project, we will be using a passive buzzer to generate sound. Similar to the active buzzer example, you will need to connect the buzzer to the Arduino. The buzzer has a positive “+” pole, which can be connected using a red wire (a good habit to follow). Connect the negative “-” wire to the GND on the Arduino and the “+” wire to a digital output pin. In this case, we will be using pin #8....

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)....
