CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY A siren is a loud noise making device. Civil defense sirens are mounted in fixed locations and used to warn of natural disasters or attacks. Sirens are used on emergency service vehicles such as ambulance, police cars and fire trucks. There are two general types of siren: 1-Pneumatic Siren 2-Electronic Siren Many fire sirens (used for calling the volunteer fire fighters) serve double ...

CHAPTER ONE INTRODUCTION 1.1 Background of the Study The primary objective of the contents of this file is to provide adequate breadth and depth for basics in electronic components at the undergraduate level. The document contains the procedure right from drawing the circuit diagram on the page to its implementation on the Printed Circuit Board. It includes the information of the basic components of electronics like the capacitor, resistor, diodes ...

CHAPTER 1 INTRODUCTION 1.1  PROJECT OVERVIEW Battery level indicator is a circuit that is used to check the battery life. We can easily recognize the battery level with the help of LED’s. It uses a LM3914 driver IC use to drive 10 leds by passing through it sufficient amount of current. Brightness of leds are controlled by reference adjustable pin and reference out pin. A variable resistor is also deployed in ...

CHAPTER ONE INTRODUCTION 1.1 Overview: Traffic lights are used to control the vehicular traffic. Now a day the road accident is increasing clay by day due to careless driving. Breaking of traffic rules. Insufficient traffic police and absence of traffic control system on the road. Everyone has different types of vehicles resulting in rise to the numbers of vehicles. Traffic light is the one of the vital public facilities plays ...

ABSTRACT This project work describes the construction and designing of 12volt car battery charger with USB port for charging mobile phones. The charging process is focus more on 12volt lead car batteries commonly used in vehicles. This design was done by using I.C LM7812 and LM7806 with transformer of 230 volt and series of other electrical component highlighted in the work to achieve our goal. The charger was able to ...
