Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

The PIR sensor successfully detected motion and triggered the Arduino to turn ON the built-in LED. The LED remained OFF when no motion was present, confirming correct circuit and code functionality.

EXP-1-b-.Automatic-Motion-Activated-Security-using-PIR-Sensor AIM: To detect motion using a PIR sensor connected to an Arduino and trigger an LED (using the built-in LED) when motion is sensed.
