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.

Arduino-based-alarm-system ⏰ this is a simple arduino based project whose working revolves around the rtc time module.

This Arduino based Real time clock is a digital clock to display real time using a RTC IC DS1307 which works on I2C protocol. Real time clock means it runs even after power failure. When power is ...

It contains an Uno DIP R3 board, which is compatible with CH340C, along with an IR sensor module equipped with a preset for precise adjustments. An active buzzer module is also included for audio ...

In this project we are going to build a Dog Barking Security Alarm using Arduino Nano, PIR Motion Sensor, and Dog Barking Sound Module.

SRKH Designs has designed and created a new processor module in the form of the microZERO SAMD CPU board that is compatible with Arduino development boards and could be the perfect processor for ...

These sensors send data to an Arduino Uno R3 microcontroller and utilize it to determine the gas concentration and trigger security precautions. When the concentration exceeds a threshold, then it ...
