Active Buzzer Schematic. Turn the pins of two buzzers face up and the one with a green circuit board is a passive buzzer while the other enclosed with a black tape is an active one. One bc548 transistor or other similar npn transistor.
Understanding some of the technologies and configurations of buzzers is useful during the design process so in this blog post we will describe typical configurations provide example buzzer tones and present common drive circuit options. The active buzzer has built in electronics that produces the buzzer sound. Alarming circuits where the user has to be alarmed about something.
A power source of course 6v to 24v.
Buzzers can be categorized into active and passive ones the schematic diagram of the module is as follows. Turn the pins of two buzzers face up and the one with a green circuit board is a passive buzzer while the other enclosed with a black tape is an active one. One self drive 3 terminal piezoelectric buzzer. Please kindly assist me to like share and subscribe our channel for more video.
