Product Description
Note that the "source" here does not refer to the power source. It refers to the source of the shock.
The features of passive buzzer are:
1 There is no oscillator inside the passive, so if you use a DC signal, you can't make it sound. Must use 2K~5K square wave to drive it
2 The frequency of the sound is controllable, and it can produce the effect of "multiple mifa Solaxi".
3 In some special cases, a control port can be reused with LED
The features of active buzzer are:
1 The active buzzer has an internal oscillation source, so it will beep as long as it is powered on
2 The program control is convenient. The single-chip microcomputer can make a sound with a high and low level, but the passive buzzer can't.
Each set weighs about 6g
A module description
1 The module is driven by a 9012 transistor
2 Working voltage 3.3V-5V
6 Equipped with fixing bolt holes for easy installation
7 Small board PCB size: 3.3cm * 1.3cm
Two module interface description (3-wire system)
1 VCC External 3.3V-5V voltage (can be directly connected with 5v single-chip microcomputer and 3.3v single-chip microcomputer)
2 GND External GND
3 I/O External MCU IO port
