Active Buzzer Module High Level Modules Compatible with Arduino DIY Kit (Active Buzzer)

The characteristics of a passive buzzer are:
 

1. There is no vibration source inside the passive source, so it cannot be made to sound if the DC signal is used. It must be driven by a square wave of 2K~5K

2. The sound frequency can be controlled, which can make the effect of "Dolemifasolasie".

3. In some special cases, you can reuse a control port with the LED
 

The characteristics of an active buzzer are:
 

1. The active buzzer has a shock source inside, so it will call as long as it is powered on

2. Convenient program control, single chip microcomputer a high and low level can make it sound, but passive buzzer can not do.

The weight of each set is about 6g
