Description

PROJECT OUTLINE:

Simple LDR circuit; use LDR and Arduino together to make milk mail indicator(aka LDR DRAK SENSOR).

WORKING:

  • A external light(LED1) that always fall on LDR when postmen/milkmen drops post or milk the light that falls on LDR gets disturbed.
  •  And signal is send to  Arduino board that process  data and make another output LED to glow.
  •  So that user/housemates gets notified to get letter/milk from Milk mail box
Working of LDR Darkness Sensor
