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 ...

This project uses a PIR (Passive Infrared) sensor to detect motion and displays the status on an I2C Liquid Crystal Display (LCD). When motion is detected, a message is shown on the LCD and printed to ...

This project demonstrates how to interface a PIR (Passive Infrared) motion sensor with an Arduino Uno R3 to detect movement and trigger an LED. When the PIR sensor detects motion, the LED turns on for ...
