ABSTRACT
The main objective of this project was to ensure a proper security to car being parked in garage against theft or an intruder. The circuit uses three NE555 timers; one of the NE555 was wired as a monostable oscillator and remaining two were wired as tone generator and amplified to obtain a maximum audible sound. However, pin 2 of the first NE555 was used as sensor part .When pin 2 has contact with human body or hand it will activate the IC1 which will also bias transistor and this transistor was wired in a way that once it is powered it will close circuit thereby passing a negative supply voltage to tone generator circuit and outputted out through a loud speaker or buzzer.
This device functions as a major security device against car-theft as stated above. It is an electronic device that is connected to the battery of the car it is being installed in and gets activated when the car engine is switched off and the car stationed at a place. The device is not seen but, it has an indicator light which shows that the alarm has been activated. When the body of the car is touched by human hand, it sends a negative signal to the device which needs a negative pulse to get activated; it sends this negative from the human hand to the tone generator IC which triggers the alarm.

CHAPTER ONE:
 INTRODUCTION
1.1.        Background of the Study
        The first car alarm was a primitive contraption that utilized a bell or horn connected to the drive shaft. It was created by an unnamed Nebraska inventor in June 20th, 1920. It utilizes the drive shaft to operate its own bell or horn signal when the car is properly moved. This is just a little talk on a car alarm but not a car touch intruder alarm which is a modern, more advanced, and more reliable type of car alarm.
        This car touch sensitive alarm project consist of three NE555 timer IC, the first NE555 was wired as monostable  multi-vibrator and the remaining two were wired as tone generator. When the sensor is touch or has contact with human hand perhaps body, IC1 is triggered at its pin 2 and output pin 3 goes high for a time period previously set by the values of R4 (10M) and Q1 (transistor) was bias via R3 and this transistor is in such a way that once it was biased it will supply a negative voltage to tone generator thereby making two NE555 timer which was know as (tone generator) to oscillate to...
