Resistor 100ohm. An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage. An active buzzer can be controlled from an Arduino pin, very similar to the way you turn on and off an LED using digitalWrite. The KY-012 Active Buzzer module consists of an active piezoelectric buzzer, it generates a sound of aproximately 2.5kHz when signal is high. Connect signal (S) to pin 8 on the Arduino and Ground (-) to GND. Though simple to use, the downside of the active buzzer is that the tone of the buzzer is fixed at a particular frequency and the loudness is more or less fixed. There are different types of security systems available and laser based security system is an important and efficient type. So basically the buzzer, 1 k ohm resistor and Arduino should be connected like this: Arduino digital pin 3 –> Buzzer –> 1 k ohm resister –> Arduino ground (GND) pin. On the other hand, a passive buzzer requires a signal source, which will set the sound signal parameters. By primerobotics Follow. One advantage to an active buzzer is that you can still produce a sound from the buzzer connected to a microcontroller, such as an Arduino, by just driving a standard high output on the connected pin.
