Prototyping PCB Prototype Shield UNO R3 ProtoShield With Mini Breadboard

Product Specification:

Product Description:

There are many people active and passive buzzer buzzer concept is not very clear, here to do a brief introduction, we want to be helpful for future use.

Note that the "source" does not mean power. But rather refers to the shock source.

Passive buzzer is characterized by:

A passive internal sources without shocks, so if the DC signal can not make it with a tweet. Must 2K ~ 5K square wave to drive it

Sound frequency controllable, you can make a "more than a meter hair Suola Xi" effect.

In some special cases, you can reuse a control and LED mouth

Active buzzer is characterized by:

An active internal buzzer with shock source, so long as a power will be called

Program easy to control, SCM can allow a high and low sounds, while passive buzzer can not.
