Basics of Arduino - Sound Control with Active Buzzer

Please click this link for the code and schematic diagram: bit.ly/2NSosDM Basics of Arduino - Sound Control with Active Buzzer I am using in this project an active buzzer to make sound. By definition, an active buzzer has a built-in oscillating source, so it will make sounds when electrified. It is often more expensive than passive buzzer because of multiple built-in oscillating circuits. Music by: https://www.free-stock-music.com
