Atmega Arduino LED DIMMER PIR motion sensor light This program is useful for creating an energy-efficient lighting system that responds to motion, such as a hallway or security light, with adjustable ...

Initialization: Sets up pin modes for the LED, PIR sensor, and piezo buzzer. Begins serial communication with a baud rate of 9600. Delays for 5 seconds to ensure stable start-up. Motion Detection: ...

The real-time PIR sensor in Proteus senses the motion of a particular area. As Proteus is the EDA, to show the motion, a TestPin is present on the sensor. I used the toggle pin here to indicate the ...
