Abstract


Motion Detector On
Mading With Automatic Lights And LED Status based mi-
crocontroller of Atmega - 89S51 is a system that can turn on
lights automatically. This tool uses PIR sensor, PIR sensor
at the input of a movement, then the Atmega 89S51 will
process the input provided by the PIR sensor to automati-
cally turn on the lights. This tool also uses a LED indicator
that is used so that readers can nd out how long the lights
will be o. This indicator using 5 pieces LED, where the
