Introduction to Buzzers with Arduino | Task 1

In this lesson we will learn about passive and active buzzers.

Think of buzzers as devices that make noise in your Arduino projects, like a simple musical instrument. There are two main types: passive and active buzzers, and they work a bit differently.

Passive Buzzer: Imagine a passive buzzer as a speaker that can only make one sound at a time. To play different notes, you must turn it on and off quickly in your code. It relies on your program to generate the timing for different tones.

Active Buzzer: Picture an active buzzer as a device that can play sounds on its own. You just tell it when to start or stop, and it handles the rest. It has built-in electronics to produce different frequencies without your code managing timing.

In short: passive buzzers need your code to generate sounds, while active buzzers can make sounds with simple commands. Choose based on how much control and simplicity you want.
