    Active Buzzer Alarm Module Sensor Beep for arduino smart car
    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...
