There is a pretty huge amount of code in this Sketch. Just press the “Copy” button on the top right of the code text field for it to automatically highlight the whole code for you. /* Arduino Mario Bros Tunes With Piezo Buzzer and PWM Connect the positive side of the Buzzer to pin...
There are two kinds of piezo buzzers: active and passive. The active one that plays a specific pitch when powevered and is not good for this purpose. The passive kind functions like a speaker, reproducing the pitch you apply to it. You can test the piezo speaker with the "blink" ...
