Description
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
