CHAPTER ONE - [ Total Page(s): 2 ]OBJECTIVE OF THE PROJECTAlarms are frequently used for detecting the presence of an intruder. These include signaling the presence of unwanted moisture or liquids, presence or absence of light, the removal of a small object, the unwanted opening of a door, power outage, and presence of an unwanted signal in an electronic gadgets etc.Most electronics alarms are either activated when a circuit is opened or short circuited. However, the aim or objective of the project is to build a multi-purpose al ... Continue reading---
