This Arduino sketch plays a melody using the components mentioned above. The melody is defined in the code using an array of note frequencies (melody[]) and note durations (durations[]). The pitches.h library is included to define the note frequencies.
The setup() function sets the BUZZER_PIN (Pin 7) as an output pin.
The loop() function iterates over the notes defined in the melody[] and durations[] arrays. For each note, it calculates the note duration and plays the tone using the tone() function. After playing each note, it waits for a pause duration before proceeding to the next note.
- Connect the components as per the provided circuit diagram.
- Upload the code to your Arduino Uno board.
- Power on the Arduino Uno.
The melody will start playing on the speaker connected to the circuit.
This code was designed by Prince Kushwaha.
