This file contains the code to play the "Pirates of the Caribbean" Theme Song on a Arduino via a Buzzer

Youtube in action: https://www.youtube.com/watch?v=sjPAj1lXgtk

1. Download Pirates_of_the_Caribbean_-_Theme_Song.ino

2. Connect Pin 10 of the Arduino to the positive side of a buzzer or a microphone

3. Connect any resistor (220 ohms for example) to the negative side of a buzzer and to the ground pin of the Arduino

4. Upload the sketch and enjoy!

Don't have an Arduino with you right now? No worry. You can test it virtually on my simulated TinkerCAD circuit.

1. Click Simulate

2. Click Start Simulation and enjoy!

🚀Happy engineering and designing!

This project was first created in 2016. It is recently updated on 2021.03.25, 5 years later. I know, sorry, I lost track of it, lol. There are a couple of improvements that can be made and have been made with this update:

1. You can remove the paper seal on the buzzer to make it sound better (Thanks Ricardo Moreno for the suggestion)

2. songSpeed and wait are converted to float type (Thanks Andrew Lalis for catching the bug)

3. noTone is used to handle malperformance of some Arduinos (Thanks Anthony Pelletier for bringing up this issue)

4. In my previous comment, I said you can only use PWM pins for the buzzer. That is not true and has been corrected. You can use any digital pin pin 0-13. The tone library uses a hardware timer and a timer interrupt to generate a square wave with different frequency, so it works on any digital pin. Beware that this might interfere with PWM when you use analogWrite because PWM also uses a timer.

5. Better coding style, format, variable names... (I have learned a lot more about coding since I first exposed to C++ 5 years ago)
