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 uses an Arduino Uno to build a burglar detection alarm system with a PIR sensor. The system triggers an alarm when motion is detected, signaling with an LED and a piezo buzzer. This code ...

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 ...
