Video 10: Arrays and Piezo Buzzers | Playing Musical Tones

This tutorial dives into the essentials of using arrays and generating musical tones with a piezo buzzer in Arduino programming, demonstrated through a musical tone project.

• Piezo Buzzers: Explains how piezo buzzers work and how different frequencies produce musical tones.

• Tone Function: Demonstrates the use of the tone function to generate different frequencies and produce sounds.

• Arrays in Arduino: Introduces arrays to organize data efficiently, simplifying the code by reducing repetitive variable declarations and hard-coded values.

• Array and Loop Implementation: Shows how to use arrays and loops to handle multiple musical notes and durations, making the code more scalable and easier to maintain.

• Challenge Activity: Provides a task to modify the program to adjust the song’s tempo using a potentiometer, encouraging practical application of the concepts learned.

• Challenge Activity: Modify the program to allow users to adjust the song’s speed using a potentiometer and create a new song of your choice.
