This project uses an Arduino board with a PIR motion sensor to detect movement. When motion is detected, an LED lights up and a buzzer sounds. It's ideal for simple security systems or motion-based ...

Code to control an LED connected to pin 8 of the Arduino Uno based on input from a PIR motion sensor connected to pin 9. The LED turns on when motion is detected (HIGH signal) and turns off when no ...

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 ...

Abstract: In India, nearly 20 percent of the electricity is lost due to technical and commercial reasons. Three billion units of power are wasted every year. The Automation of lighting system with the ...
