In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

A Simple Beginner Arduino Code for sensing the presence of humans using PIR Sensor with a time limit. Here, We have used a 20 by 4 LCD Display and a PIR Sensor. When the PIR senses movement using IR ...

const int pirPin2 = 5; // Digital pin connected to the second PIR sensor int pirState1 = digitalRead(pirPin1); // Read the state of the first sensor int pirState2 = digitalRead(pirPin2); // Read the ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

Abstract: In an era where homeowners frequently leave for work or education, robust security for residences is imperative. Traditional security measures, including window and door locks, present ...
