This project demonstrates how to use a buzzer module with an Arduino Nano to produce sound or generate alerts. Buzzer modules can be either active or passive, each requiring different driving methods.

The schematic for the Dog Barking Alarm using Arduino is given below. The Amplifier IC is used to amplify the Output from Dog Barking Sound Module. The Alarm circuit consists of an Arduino Nano, PIR ...

In this tutorial, we will build a basic rain sensor using Arduino with a buzzer. You can then use this set-up to build anything you wish on top of it. Also, note that the rain sensor module is also ...

- Buzzer: A piezo buzzer generates sound signals for the audible alarm. - Programming Language: The project is coded in the Arduino programming language (a subset of C/C++). Project Workflow: 1.

If you’re bit-less, they’re also now selling an Arduino-centric starter kit with the Arduino module and 8 others (a battery, a few switches, a servo, and a control dial) for $89.

When reed switch is opened, pin 2 of Arduino goes high with the help of the pull-up resistor R2, and the alert signal is available through the piezo-speaker PZ1 (not an active piezo-buzzer). At the ...
