SPECIFICATIONS

Passive Buzzer Module

Arduino Passive Piezoelectric Buzzer Module can produce a range of sound tones depending on the input frequency. It consists of a passive piezoelectric buzzer, it can generate tones between 1.5 to 2.5 kHz by switching it on and off at different frequencies either using delays or PWM.

• Operating Voltage: 1.5~15V DC
• Tone Generation Range: 1.5~2.5kHz
• Dimensions: 18.5mm*15mm

Arduino Uno

CIRCUIT CONNECTION

WORKING

Welcome to the Arduino Based Project which consists of Passive Buzzer. The basic working principle of Passive buzzer is being described here. A passive buzzer requires an AC signal to make a sound. It is like an electromagnetic speaker, where a changing input signal produces the sound, rather than producing a tone automatically.

Here, we have generated a tone from Passive buzzer. It can be done by PWM on the Arduino which can be used to control the pitch and the volume at the same time.
