This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

We can make an intruder alarm circuit at home which will be almost equally efficient for a specific range of distance and will be very low in cost. This article is about making an intruder alarm using ...

The tilt sensor is a component that can detect the tilting of an object. However it is only the equivalent to a pushbutton activated through a different physical mechanism. This type of sensor is the ...

led, and active buzzer. Which is going to be connected to the Arduino GPIO pins. /* ===== Ultrasonic Sensor Data ===== */ long duration = 0; // Duration of ultrasonic signal bounce-back (in ...

The 5V and GND pins on the Arduino UNO Board are used, and the Sensor's output pin is linked to the A0 pin on the Arduino. We have connected an LED and a buzzer to digital PIN 7 of the Arduino, the ...

Motion sensor alarms are readily available in the market, but these are expensive. Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert ... the sample audio file and ...

so this research proposes a multi-sensor integrated intelligent alarm system based on Arduino. This paper presents the design and implementation of a multi-sensor integrated smart alarm system based ...
