SPECIFICATIONS

Buzzer Module

Active Buzzer Module produces a single-tone sound when signal is high. To produce different tones use the Passive Buzzer Module. It consists of an active piezoelectric buzzer, it generates a sound of approximately 2.5 kHz when signal is high.

WORKING

Welcome to the Arduino Based Project which consists of Passive Buzzer. The basic working principle of Buzzer is being described here. After uploading the code, when you press the button, Buzzer module generates sound due to the internal oscillation. The buzzer module which will change the frequency of tone from High to Low volume after every button pressed.
